  • Calling a WCF WebService in PHP via wsHttpBinding.

    - by Justin Dearing
    I have a WCF webservice I can connect to it via basicHttp, but not wsHttp. I try to conenct to it via wshttp via the following: $service = new SoapClient ("http://service.companyname.local:6666/Service/?wsdl", array( "location" => "http://service.companyname.local:6666/Service/WCF", "trace" => true, 'soap_version' => SOAP_1_2 ) ); The call to the SoapClient constructor returns fine. When I try to call one using $client-FunctionName, the page just sits there loading for quite a while, and eventually returns the error "Error Fetching http headers". What exactly is this supposed to mean and how do I fix it? (Consuming the service from .Net client works perfectly.)

  • WCF client hangs on response

    - by JohnIdol
    I have a WCF client (running on Win7) pointing to a WebSphere service. All is good from a test harness (a little test fixture outside my web app) but when my calls to the service originate from my web project one of the calls is extremely slow to deserialize (it takes up to 10 times longer) and not just the first time. I can see from fiddler that the response comes back quickly but then the WCF client hangs on the response itself for more than a minute before the next line of code is hit by the debugger, almost if the client was having trouble deserializing. This happens only if in the response I have a given pdf string, base64 encoded chunked. If for example the service raises a fault (this pdf string is not there) then the response is deserialized immediately. Again, If I send the exact same envelope through Soap-UI or from outside the web project all is good. I am at loss - What should I be looking for and is there some config setting that might do the trick? Any help appreciated!

  • Windows Phone 7 Application + WCF + SSL + Username Authentication

    - by s7orm
    Hello, I have developed a test service with WCF, which I try to consume from a Windows Phone 7 Application, however when calling a method from the service I get a weird exception: There was no endpoint listening at https://server/Service.svc that could accept the message. This is often caused by an incorrect address or SOAP action. The WCF service uses a custom binding with UserNameOverTransport authentication and SSL. For the authorization I am using an implementation of the UserNamePasswordValidator. If I try to consume the service from a console or silverlight application (cross domain policy is enabled) - it works fine (authorization as well). And the most weird thing is that the ServiceReferences.ClientConfig file generated for the WP7 App is exactly the same as the config file generated for the silverlight application. I have no idea what is wrong with my service...

  • Queued WCF Service which processes every X seconds

    - by Jeff Windsor
    I need to create a service which can process queued requests on a configured time interval. For example go to the web and get financial data from a site the requires we limit requests to once per second. I am new to WCF and I am not sure if (1) WCF with MSMQ a proper choice for implementing this? and (2) if so what is the best mechanism for enforcing the interval? a thread wait? a timer (not sure how that would work).

  • ASP.net and WCF some clarification

    - by nettguy
    Recently I faced few interview questions.The interviewer asked the to give the detailed answer. 1)Can we override a WCF service (Its is not OOPS overriding) ?.Explain the reason on either end. (WCF Related). 2)Can we override Page events (Page_Load())?.Explain reason.(ASP.NET related). 3)What is the primary responsibility of Pre_Init( page) event ,apart from user preference setting,skinning? 4) Can we override Static methods.Explain the reason. can anyone help me to understand the reasons.Thanks in well advance.

  • JSONP parsing error from WCF

    - by user1754730
    Answered my own question I had a problem with a jquery (jsonp) call to a WCF service that was throwing a json parsing error. Using ASP.NET 4.0 on the WCF side and jquery 1.7 on the client side. Turned out there was an old set of script tags on the page using language = VBSCRIPT. The browser was interpreting the returned json packet of script as "VBscript" instead of javascript. I placed a set of empty javascript tags at the top of the page and the browser is now interpreting the json as the proper javascript function. Hope this helps someone else. Tom

  • Property overwrite behaviour

    - by jeremyj
    I thought it worth sharing about property overwrite behaviour because i found it confusing at first in the hope of preventing some learning pain for the uninitiated with MSBuild :-)The confusion for me came because of the redundancy of using a Condition statement in a _project_ level property to test that a property has not been previously set. What i mean is that the following two statements are always identical in behaviour, regardless if the property has been supplied on the command line -  <PropertyGroup>    <PropA Condition=" '$(PropA)' == '' ">PropA set at project level</PropA>  </PropertyGroup>has the same behaviour regardless of command line override as -  <PropertyGroup>     <PropA>PropA set at project level</PropA>   </PropertyGroup>  i.e. the two above property declarations have the same result whether the property is overridden on the command line or not.To prove this experiment with the following .proj file -<?xml version="1.0" encoding="utf-8"?><Project ToolsVersion="4.0" >  <PropertyGroup>    <PropA Condition=" '$(PropA)' == '' ">PropA set at project level</PropA>  </PropertyGroup>  <Target Name="Target1">    <Message Text="PropA: $(PropA)"/>  </Target>  <Target Name="Target2">    <PropertyGroup>      <PropA>PropA set in Target2</PropA>    </PropertyGroup>    <Message Text="PropA: $(PropA)"/>  </Target>  <Target Name="Target3">    <PropertyGroup>      <PropA Condition=" '$(PropA)' == '' ">PropA set in Target3</PropA>    </PropertyGroup>    <Message Text="PropA: $(PropA)"/>  </Target>  <Target Name="Target4">    <PropertyGroup>      <PropA Condition=" '$(PropA)' != '' ">PropA set in Target4</PropA>    </PropertyGroup>    <Message Text="PropA: $(PropA)"/>  </Target></Project>Try invoking it using both of the following invocations and observe its output -1)>msbuild blog.proj /t:Target1;Target2;Target3;Target42)>msbuild blog.proj /t:Target1;Target2;Target3;Target4 "/p:PropA=PropA set on command line"Then try those two invocations with the following three variations of specifying PropA at the project level -1)  <PropertyGroup>     <PropA Condition=" '$(PropA)' == '' ">PropA set at project level</PropA>   </PropertyGroup> 2)   <PropertyGroup>     <PropA>PropA set at project level</PropA>   </PropertyGroup>3)  <PropertyGroup>     <PropA Condition=" '$(PropA)' != '' ">PropA set at project level</PropA>   </PropertyGroup>

  • Very slow performance deserializing using datacontractserializer in a Silverlight Application.

    - by caryden
    Here is the situation: Silverlight 3 Application hits an asp.net hosted WCF service to get a list of items to display in a grid. Once the list is brought down to the client it is cached in IsolatedStorage. This is done by using the DataContractSerializer to serialize all of these objects to a stream which is then zipped and then encrypted. When the application is relaunched, it first loads from the cache (reversing the process above) and the deserializes the objects using the DataContractSerializer.ReadObject() method. All of this was working wonderfully under all scenarios until recently with the entire "load from cache" path (decrypt/unzip/deserialize) taking hundreds of milliseconds at most. On some development machines but not all (all machines Windows 7) the deserialize process - that is the call to ReadObject(stream) takes several minutes an seems to lock up the entire machine BUT ONLY WHEN RUNNING IN THE DEBUGGER in VS2008. Running the Debug configuration code outside the debugger has no problem. One thing that seems to look suspicious is that when you turn on stop on Exceptions, you can see that the ReadObject() throws many, many System.FormatException's indicating that a number was not in the correct format. When I turn off "Just My Code" thousands of these get dumped to the screen. None go unhandled. These occur both on the read back from the cache AND on a deserialization at the conclusion of a web service call to get the data from the WCF Service. HOWEVER, these same exceptions occur on my laptop development machine that does not experience the slowness at all. And FWIW, my laptop is really old and my desktop is a 4 core, 6GB RAM beast. Again, no problems unless running under the debugger in VS2008. Anyone else seem this? Any thoughts? Here is the bug report link: https://connect.microsoft.com/VisualStudio/feedback/details/539609/very-slow-performance-deserializing-using-datacontractserializer-in-a-silverlight-application-only-in-debugger

  • MessageSecurityException: The security header element 'Timestamp' with the '' id must be signed

    - by NiklasN
    I'm asking the same question here that I've already asked on msdn forums http://social.msdn.microsoft.com/Forums/en-US/netfxnetcom/thread/70f40a4c-8399-4629-9bfc-146524334daf I'm consuming a (most likely Java based) Web Service with I have absolutely no access to modify. It won't be modified even though I would ask them (it's a nation wide system). I've written the client with WCF. Here's some code: CustomBinding binding = new CustomBinding(); AsymmetricSecurityBindingElement element = SecurityBindingElement.CreateMutualCertificateDuplexBindingElement(MessageSecurityVersion.WSSecurity10WSTrustFebruary2005WSSecureConversationFebruary2005WSSecurityPolicy11BasicSecurityProfile10); element.AllowSerializedSigningTokenOnReply = true; element.SetKeyDerivation(false); element.IncludeTimestamp = true; element.KeyEntropyMode = SecurityKeyEntropyMode.ClientEntropy; element.MessageProtectionOrder = System.ServiceModel.Security.MessageProtectionOrder.SignBeforeEncrypt; element.LocalClientSettings.IdentityVerifier = new CustomIdentityVerifier(); element.SecurityHeaderLayout = SecurityHeaderLayout.Lax; element.IncludeTimestamp = false; binding.Elements.Add(element); binding.Elements.Add(new TextMessageEncodingBindingElement(MessageVersion.Soap11, Encoding.UTF8)); binding.Elements.Add(new HttpsTransportBindingElement()); EndpointAddress address = new EndpointAddress(new Uri("url")); ChannelFactory<MyPortTypeChannel> factory = new ChannelFactory<MyPortTypeChannel>(binding, address); ClientCredentials credentials = factory.Endpoint.Behaviors.Find<ClientCredentials>(); credentials.ClientCertificate.Certificate = myClientCert; credentials.ServiceCertificate.DefaultCertificate = myServiceCert; credentials.ServiceCertificate.Authentication.CertificateValidationMode = X509CertificateValidationMode.None; service = factory.CreateChannel(); After this every request done to the service fails in client side (I can confirm my request is accepted by the service and a sane response is being returned) I always get the following exception MessageSecurityException: The security header element 'Timestamp' with the '' id must be signed. By looking at trace I can see that in the response there really is a timestamp element, but in the security section there is only a signature for body. Can I somehow make WCF to ingore the fact Timestamp isn't signed?

  • Creating object/array to method in request based on __gettypes in PHP

    - by LochNess
    I'm having trouble with the array or object that should be passed based on the response from __gettypes. The __gettypes response: [0] => struct CDataWrapper { schema;any; } [1] => struct NewMember { MemberDetail MemberDetails;ArrayOfHobby Hobbies; } [2] => struct MemberDetail { string Name; string Age; string Sex; } [3] => struct ArrayOfHobby { Hobby Hobby; } [4] => struct Hobby { string Name; string HoursUsedOnHobbyWeekly;boolean Favourite; } ... etc. The methods are: [0] => ReceiveMemberResponse ReceiveMember(ReceiveMember $parameters) [1] => ReturnMemberResponse ReturnMember(ReturnMember $parameters) So far I have this PHP: $client = new SoapClient('http://domain.com?wsdl'); class MemberDetail { public $Name = ''; public $Age = ''; public $Sex = ''; } $mc = new MemberDetail(); $mc->Name= 'Bob'; $mc->Age= '14'; $mc->Sex= 'Male'; $myParam = array('ReceiveMember'=>$mc); $wcf = $client->ReceiveMember($myParam); $wcfResult = $wcf->ReturnMember; print_r($wcfResult) when i call the page it returns: Error 324 (net::ERR_EMPTY_RESPONSE): Unknown error. I'm not really sure how to create the array or object to pass on as $myParam since im no expert with PHP either.

  • Another Marketing Conference, part one – the best morning sessions.

    - by Roger Hart
    Yesterday I went to Another Marketing Conference. I honestly can’t tell if the title is just tipping over into smug, but in the balance of things that doesn’t matter, because it was a good conference. There was an enjoyable blend of theoretical and practical, and enough inter-disciplinary spread to keep my inner dilettante grinning from ear to ear. Sure, there was a bumpy bit in the middle, with two back-to-back sales pitches and a rather thin overview of the state of the web. But the signal:noise ratio at AMC2012 was impressively high. Here’s the first part of my write-up of the sessions. It’s a bit of a mammoth. It’s also a bit of a mash-up of what was said and what I thought about it. I’ll add links to the videos and slides from the sessions as they become available. Although it was in the morning session, I’ve not included Vanessa Northam’s session on the power of internal comms to build brand ambassadors. It’ll be in the next roundup, as this is already pushing 2.5k words. First, the important stuff. I was keeping a tally, and nobody said “synergy” or “leverage”. I did, however, hear the term “marketeers” six times. Shame on you – you know who you are. 1 – Branding in a post-digital world, Graham Hales This initially looked like being a sales presentation for Interbrand, but Graham pulled it out of the bag a few minutes in. He introduced a model for brand management that was essentially Plan >> Do >> Check >> Act, with Do and Check rolled up together, and went on to stress that this looks like on overall business management model for a reason. Brand has to be part of your overall business strategy and metrics if you’re going to care about it at all. This was the first iteration of what proved to be one of the event’s emergent themes: do it throughout the stack or don’t bother. Graham went on to remind us that brands, in so far as they are owned at all, are owned by and co-created with our customers. Advertising can offer a message to customers, but they provide the expression of a brand. This was a preface to talking about an increasingly chaotic marketplace, with increasingly hard-to-manage purchase processes. Services like Amazon reviews and TripAdvisor (four presenters would make this point) saturate customers with information, and give them a kind of vigilante power to comment on and define brands. Consequentially, they experience a number of “moments of deflection” in our sales funnels. Our control is lessened, and failure to engage can negatively-impact buying decisions increasingly poorly. The clearest example given was the failure of NatWest’s “caring bank” campaign, where staff in branches, customer support, and online presences didn’t align. A discontinuity of experience basically made the campaign worthless, and disgruntled customers talked about it loudly on social media. This in turn presented an opportunity to engage and show caring, but that wasn’t taken. What I took away was that brand (co)creation is ongoing and needs monitoring and metrics. But reciprocally, given you get what you measure, strategy and metrics must include brand if any kind of branding is to work at all. Campaigns and messages must permeate product and service design. What that doesn’t mean (and Graham didn’t say it did) is putting Marketing at the top of the pyramid, and having them bawl demands at Product Management, Support, and Development like an entitled toddler. It’s going to have to be collaborative, and session 6 on internal comms handled this really well. The main thing missing here was substantiating data, and the main question I found myself chewing on was: if we’re building brands collaboratively and in the open, what about the cultural politics of trolling? 2 – Challenging our core beliefs about human behaviour, Mark Earls This was definitely the best show of the day. It was also some of the best content. Mark talked us through nudging, behavioural economics, and some key misconceptions around decision making. Basically, people aren’t rational, they’re petty, reactive, emotional sacks of meat, and they’ll go where they’re led. Comforting stuff. Examples given were the spread of the London Riots and the “discovery” of the mountains of Kong, and the popularity of Susan Boyle, which, in turn made me think about Per Mollerup’s concept of “social wayshowing”. Mark boiled his thoughts down into four key points which I completely failed to write down word for word: People do, then think – Changing minds to change behaviour doesn’t work. Post-rationalization rules the day. See also: mere exposure effects. Spock < Kirk - Emotional/intuitive comes first, then we rationalize impulses. The non-thinking, emotive, reactive processes run much faster than the deliberative ones. People are not really rational decision makers, so  intervening with information may not be appropriate. Maximisers or satisficers? – Related to the last point. People do not consistently, rationally, maximise. When faced with an abundance of choice, they prefer to satisfice than evaluate, and will often follow social leads rather than think. Things tend to converge – Behaviour trends to a consensus normal. When faced with choices people overwhelmingly just do what they see others doing. Humans are extraordinarily good at mirroring behaviours and receiving influence. People “outsource the cognitive load” of choices to the crowd. Mark’s headline quote was probably “the real influence happens at the table next to you”. Reference examples, word of mouth, and social influence are tremendously important, and so talking about product experiences may be more important than talking about products. This reminded me of Kathy Sierra’s “creating bad-ass users” concept of designing to make people more awesome rather than products they like. If we can expose user-awesome, and make sharing easy, we can normalise the behaviours we want. If we normalize the behaviours we want, people should make and post-rationalize the buying decisions we want.  Where we need to be: “A bigger boy made me do it” Where we are: “a wizard did it and ran away” However, it’s worth bearing in mind that some purchasing decisions are personal and informed rather than social and reactive. There’s a quadrant diagram, in fact. What was really interesting, though, towards the end of the talk, was some advice for working out how social your products might be. The standard technology adoption lifecycle graph is essentially about social product diffusion. So this idea isn’t really new. Geoffrey Moore’s “chasm” idea may not strictly apply. However, his concepts of beachheads and reference segments are exactly what is required to normalize and thus enable purchase decisions (behaviour change). The final thing is that in only very few categories does a better product actually affect purchase decision. Where the choice is personal and informed, this is true. But where it’s personal and impulsive, or in any way social, “better” is trumped by popularity, endorsement, or “point of sale salience”. UX, UCD, and e-commerce know this to be true. A better (and easier) experience will always beat “more features”. Easy to use, and easy to observe being used will beat “what the user says they want”. This made me think about the astounding stickiness of rational fallacies, “common sense” and the pathological willful simplifications of the media. Rational fallacies seem like they’re basically the heuristics we use for post-rationalization. If I were profoundly grimy and cynical, I’d suggest deploying a boat-load in our messaging, to see if they’re really as sticky and appealing as they look. 4 – Changing behaviour through communication, Stephen Donajgrodzki This was a fantastic follow up to Mark’s session. Stephen basically talked us through some tactics used in public information/health comms that implement the kind of behavioural theory Mark introduced. The session was largely about how to get people to do (good) things they’re predisposed not to do, and how communication can (and can’t) make positive interventions. A couple of things stood out, in particular “implementation intentions” and how they can be linked to goals. For example, in order to get people to check and test their smoke alarms (a goal intention, rarely actualized  an information campaign will attempt to link this activity to the clocks going back or forward (a strong implementation intention, well-actualized). The talk reinforced the idea that making behaviour changes easy and visible normalizes them and makes them more likely to succeed. To do this, they have to be embodied throughout a product and service cycle. Experiential disconnects undermine the normalization. So campaigns, products, and customer interactions must be aligned. This is underscored by the second section of the presentation, which talked about interventions and pre-conditions for change. Taking the examples of drug addiction and stopping smoking, Stephen showed us a framework for attempting (and succeeding or failing in) behaviour change. He noted that when the change is something people fundamentally want to do, and that is easy, this gets a to simpler. Coordinated, easily-observed environmental pressures create preconditions for change and build motivation. (price, pub smoking ban, ad campaigns, friend quitting, declining social acceptability) A triggering even leads to a change attempt. (getting a cold and panicking about how bad the cough is) Interventions can be made to enable an attempt (NHS services, public information, nicotine patches) If it succeeds – yay. If it fails, there’s strong negative enforcement. Triggering events seem largely personal, but messaging can intervene in the creation of preconditions and in supporting decisions. Stephen talked more about systems of thinking and “bounded rationality”. The idea being that to enable change you need to break through “automatic” thinking into “reflective” thinking. Disruption and emotion are great tools for this, but that is only the start of the process. It occurs to me that a great deal of market research is focused on determining triggers rather than analysing necessary preconditions. Although they are presumably related. The final section talked about setting goals. Marketing goals are often seen as deriving directly from business goals. However, marketing may be unable to deliver on these directly where decision and behaviour-change processes are involved. In those cases, marketing and communication goals should be to create preconditions. They should also consider priming and norms. Content marketing and brand awareness are good first steps here, as brands can be heuristics in decision making for choice-saturated consumers, or those seeking education. 5 – The power of engaged communities and how to build them, Harriet Minter (the Guardian) The meat of this was that you need to let communities define and establish themselves, and be quick to react to their needs. Harriet had been in charge of building the Guardian’s community sites, and learned a lot about how they come together, stabilize  grow, and react. Crucially, they can’t be about sales or push messaging. A community is not just an audience. It’s essential to start with what this particular segment or tribe are interested in, then what they want to hear. Eventually you can consider – in light of this – what they might want to buy, but you can’t start with the product. A community won’t cohere around one you’re pushing. Her tips for community building were (again, sorry, not verbatim): Set goals Have some targets. Community building sounds vague and fluffy, but you can have (and adjust) concrete goals. Think like a start-up This is the “lean” stuff. Try things, fail quickly, respond. Don’t restrict platforms Let the audience choose them, and be aware of their differences. For example, LinkedIn is very different to Twitter. Track your stats Related to the first point. Keeping an eye on the numbers lets you respond. They should be qualified, however. If you want a community of enterprise decision makers, headcount alone may be a bad metric – have you got CIOs, or just people who want to get jobs by mingling with CIOs? Build brand advocates Do things to involve people and make them awesome, and they’ll cheer-lead for you. The last part really got my attention. Little bits of drive-by kindness go a long way. But more than that, genuinely helping people turns them into powerful advocates. Harriet gave an example of the Guardian engaging with an aspiring journalist on its Q&A forums. Through a series of serendipitous encounters he became a BBC producer, and now enthusiastically speaks up for the Guardian community sites. Cultivating many small, authentic, influential voices may have a better pay-off than schmoozing the big guys. This could be particularly important in the context of Mark and Stephen’s models of social, endorsement-led, and example-led decision making. There’s a lot here I haven’t covered, and it may be worth some follow-up on community building. Thoughts I was quite sceptical of nudge theory and behavioural economics. First off it sounds too good to be true, and second it sounds too sinister to permit. But I haven’t done the background reading. So I’m going to, and if it seems to hold real water, and if it’s possible to do it ethically (Stephen’s presentations suggests it may be) then it’s probably worth exploring. The message seemed to be: change what people do, and they’ll work out why afterwards. Moreover, the people around them will do it too. Make the things you want them to do extraordinarily easy and very, very visible. Normalize and support the decisions you want them to make, and they’ll make them. In practice this means not talking about the thing, but showing the user-awesome. Glib? Perhaps. But it feels worth considering. Also, if I ever run a marketing conference, I’m going to ban speakers from using examples from Apple. Quite apart from not being consistently generalizable, it’s becoming an irritating cliché.

  • Code Behaviour via Unit Tests

Symptoms included a sputtering as my car’s computer switched between gears intermittently. Imagine building up speed, then when you reach 80km/h the car magically and mysteriously decide to switch back to third or even second gear. Clearly it was confused! I managed to track down a technician, an expert in his field to help me out. As he fitted his handheld computer to some hidden port under the dash, he started to explain “These cars are quite intelligent, you know. When they sense something is wrong they run in a restrictive program which probably account for how you managed to drive here in the first place...”  I was surprised and thought this was certainly going to be an interesting test drive. The car ran smoothly down the first couple of stretches as the technician ran through routine checks. Then he said “Ok, all looking good. We need to start testing aspects of the gearbox. Inside the gearbox there are a couple of sensors. One of them is a speed sensor which talks to the computer, which in turn will decide which gear to switch to. The restrictive program avoid these sensors altogether and allow the computer to obtain its input from other [non-affected] sources”. Then, as soon as he forced the speed sensor to come back online the symptoms and ill behaviour re-emerged... What an incredible analogy for getting into a discussion on unit testing software? Besides I should probably put my ill fortune to some good use, right? This example provide a lot of insight into how and why we should conduct unit tests when writing code. More importantly, it captures what is easily and unfortunately often the most overlooked goal of writing unit tests by those new to the art and those who oppose it alike - The goal of writing unit tests is to test the behaviour of our code under predefined conditions. Although it is very possible to test the intrinsic workings of each and every component in your code, writing several tests for each method in practise will soon prove to be an exhausting and ultimately fruitless exercise given the certain and ever changing nature of business requirements. Consequently it is true and quite possible whilst conducting proper unit tests, to call any single method several times as you examine and contemplate different scenarios. Let’s write some code to demonstrate what I mean. In my example I make use of the Moq framework and NUnit to create my tests. Truly you can use whatever you’re comfortable with. First we’ll create an ISpeedSensor interface. This is to represent the speed sensor located in the gearbox.  Then we’ll create a Gearbox class which we’ll pass to a constructor when we instantiate an object of type Computer. All three are described below.   ISpeedSensor.cs namespace AutomaticVehicle {     public interface ISpeedSensor     {         int ReportCurrentSpeed();     } }   Gearbox.cs namespace AutomaticVehicle {      public class Gearbox     {         private ISpeedSensor _speedSensor;           public Gearbox( ISpeedSensor gearboxSpeedSensor )         {             _speedSensor = gearboxSpeedSensor;         }         /// <summary>         /// This method obtain it's reading from the speed sensor.         /// </summary>         /// <returns></returns>         public int ReportCurrentSpeed()         {             return _speedSensor.ReportCurrentSpeed();         }     } } Computer.cs namespace AutomaticVehicle {     public class Computer     {         private Gearbox _gearbox;         public Computer( Gearbox gearbox )         {                     }          public int GetCurrentSpeed()         {             return _gearbox.ReportCurrentSpeed( );         }     } } Since this post is about Unit testing, that is exactly what we’ll create next. Create a second project in your solution. I called mine AutomaticVehicleTests and I immediately referenced the respective nunit, moq and AutomaticVehicle dll’s. We’re going to write a test to examine what happens inside the Computer class. ComputerTests.cs namespace AutomaticVehicleTests {     [TestFixture]     public class ComputerTests     {         [Test]         public void Computer_Gearbox_SpeedSensor_DoesThrow()         {             // Mock ISpeedSensor in gearbox             Mock< ISpeedSensor > speedSensor = new Mock< ISpeedSensor >( );             speedSensor.Setup( n => n.ReportCurrentSpeed() ).Throws<Exception>();             Gearbox gearbox = new Gearbox( speedSensor.Object );               // Create Computer instance to test it's behaviour  towards an exception in gearbox             Computer carComputer = new Computer( gearbox );             // For simplicity let’s assume for now the car only travels at 60 km/h.             Assert.AreEqual( 60, carComputer.GetCurrentSpeed( ) );          }     } }   What is happening in this test? We have created a mocked object using the ISpeedsensor interface which we've passed to our Gearbox object. Notice that I created the mocked object using an interface, not the implementation. I’ll talk more about this in future posts but in short I do this to accentuate the fact that I'm not not really concerned with how SpeedSensor work internally at this particular point in time. Next I’ve gone ahead and created a scenario where I’ve declared the speed sensor in Gearbox to be faulty by forcing it to throw an exception should we ask Gearbox to report on its current speed. Sneaky, sneaky. This test is a simulation of how things may behave in the real world. Inevitability things break, whether it’s caused by mechanical failure, some logical error on your part or a fellow developer which didn’t consult the documentation (or the lack thereof ) - whether you’re calling a speed sensor, making a call to a database, calling a web service or just trying to write a file to disk. It’s a scenario I’ve created and this test is about how the code within the Computer instance will behave towards any such error as I’ve depicted. Now, if you’ve followed closely in my final assert method you would have noticed I did something quite unexpected. I might be getting ahead of myself now but I’m testing to see if the value returned is equal to what I expect it to be under perfect conditions – I’m not testing to see if an error has been thrown! Why is that? Well, in short this is TDD. Test Driven Development is about first writing your test to define the result we want, then to go back and change the implementation within your class to obtain the desired output (I need to make sure I can drive back to the repair shop. Remember? ) So let’s go ahead and run our test as is. It’s fails miserably... Good! Let’s go back to our Computer class and make a small change to the GetCurrentSpeed method.   Computer.cs public int GetCurrentSpeed() {   try   {     return _gearbox.ReportCurrentSpeed( );   }   catch   {     RunRestrictiveProgram( );   } }     This is a simple solution, I know, but it does provide a way to allow for different behaviour. You’re more than welcome to provide an implementation for RunRestrictiveProgram should you feel the need to. It's not within the scope of this post or related to the point I'm trying to make. What is important is to notice how the focus has shifted in our approach from how things can break - to how things behave when broken.   Happy coding!

  • Unity falling body pendulum behaviour

    - by user3447980
    I wonder if someone could provide some guidance. Im attempting to create a pendulum like behaviour in 2D space in Unity without using a hinge joint. Essentially I want to affect a falling body to act as though it were restrained at the radius of a point, and to be subject to gravity and friction etc. Ive tried many modifications of this code, and have come up with some cool 'strange-attractor' like behaviour but i cannot for the life of me create a realistic pendulum like action. This is what I have so far: startingposition = transform.position; //Get start position newposition = startingposition + velocity; //add old velocity newposition.y -= gravity * Time.deltaTime; //add gravity newposition = pivot + Vector2.ClampMagnitude(newposition-pivot,radius); //clamp body at radius??? velocity = newposition-startingposition; //Get new velocity transform.Translate (velocity * Time.deltaTime, Space.World); //apply to transform So im working out the new position based on the old velocity + gravity, then constraining it to a distance from a point, which is the element in the code i cannot get correct. Is this a logical way to go about it?

  • EF4 POCO WCF Serialization problems (no lazy loading, proxy/no proxy, circular references, etc)

    - by kdawg
    OK, I want to make sure I cover my situation and everything I've tried thoroughly. I'm pretty sure what I need/want can be done, but I haven't quite found the perfect combination for success. I'm utilizing Entity Framework 4 RTM and its POCO support. I'm looking to query for an entity (Config) that contains a many-to-many relationship with another entity (App). I turn off lazy loading and disable proxy creation for the context and explicitly load the navigation property (either through .Include() or .LoadProperty()). However, when the navigation property is loaded (that is, Apps is loaded for a given Config), the App objects that were loaded already contain references to the Configs that have been brought to memory. This creates a circular reference. Now I know the DataContractSerializer that WCF uses can handle circular references, by setting the preserveObjectReferences parameter to true. I've tried this with a couple of different attribute implementations I've found online. It is needed to prevent the "the object graph contains circular references and cannot be serialized" error. However, it doesn't prevent the serialization of the entire graph, back and forth between Config and App. If I invoke it via WcfTestClient.exe, I get a stackoverflow (ha!) exception from the client and I'm hosed. I get different results from different invocation environments (C# unit test with a local reference to the web service appears to work ok though I still can drill back and forth between Configs and Apps endlessly, but calling it from a coldfusion environment only returns the first Config in the list and errors out on the others.) My main goal is to have a serialized representation of the graph I explicitly load from EF (ie: list of Configs, each with their Apps, but no App back to Config navigation.) NOTE: I've also tried using the ProxyDataContractResolver technique and keeping the proxy creation enabled from my context. This blows up complaining about unknown types encountered. I read that the ProxyDataContractResolver didn't fully work in Beta2, but should work in RTM. For some reference, here is roughly how I'm querying the data in the service: var repo = BootStrapper.AppCtx["AppMeta.ConfigRepository"] as IRepository<Config>; repo.DisableLazyLoading(); repo.DisableProxyCreation(); //var temp2 = repo.Include(cfg => cfg.Apps).Where(cfg => cfg.Environment.Equals(environment)).ToArray(); var temp2 = repo.FindAll(cfg => cfg.Environment.Equals(environment)).ToArray(); foreach (var cfg in temp2) { repo.LoadProperty(cfg, c => c.Apps); } return temp2; I think the crux of my problem is when loading up navigation properties for POCO objects from Entity Framework 4, it prepopulates navigation properties for objects already in memory. This in turn hoses up the WCF serialization, despite every effort made to properly handle circular references. I know it's a lot of information, but it's really standing in my way of going forward with EF4/POCO in our system. I've found several articles and blogs touching upon these subjects, but for the life of me, I cannot resolve this issue. Feel free to simply ask questions and help me brainstorm this situation. PS: For the sake of being thorough, I am injecting the WCF services using the HEAD build of Spring.NET for the fix to Spring.ServiceModel.Activation.ServiceHostFactory. However I don't think this is the source of the problem.

  • WCF Data Service BeginSaveChanges not saving changes in Silverlight app

    - by Enigmativity
    I'm having a hell of a time getting WCF Data Services to work within Silverlight. I'm using the VS2010 RC. I've struggled with the cross domain issue requiring the use of clientaccesspolicy.xml & crossdomain.xml files in the web server root folder, but I just couldn't get this to work. I've resorted to putting both the Silverlight Web App & the WCF Data Service in the same project to get past this issue, but any advice here would be good. But now that I can actually see my data coming from the database and being displayed in a data grid within Silverlight I thought my troubles were over - but no. I can edit the data and the in-memory entity is changing, but when I call BeginSaveChanges (with the appropriate async EndSaveChangescall) I get no errors, but no data updates in the database. Here's my WCF Data Services code: public class MyDataService : DataService<MyEntities> { public static void InitializeService(DataServiceConfiguration config) { config.SetEntitySetAccessRule("*", EntitySetRights.All); config.SetServiceOperationAccessRule("*", ServiceOperationRights.All); config.DataServiceBehavior.MaxProtocolVersion = DataServiceProtocolVersion.V2; } protected override void OnStartProcessingRequest(ProcessRequestArgs args) { base.OnStartProcessingRequest(args); HttpContext context = HttpContext.Current; HttpCachePolicy c = HttpContext.Current.Response.Cache; c.SetCacheability(HttpCacheability.ServerAndPrivate); c.SetExpires(HttpContext.Current.Timestamp.AddSeconds(60)); c.VaryByHeaders["Accept"] = true; c.VaryByHeaders["Accept-Charset"] = true; c.VaryByHeaders["Accept-Encoding"] = true; c.VaryByParams["*"] = true; } } I've pinched the OnStartProcessingRequest code from Scott Hanselman's article Creating an OData API for StackOverflow including XML and JSON in 30 minutes. Here's my code from my Silverlight app: private MyEntities _wcfDataServicesEntities; private CollectionViewSource _customersViewSource; private ObservableCollection<Customer> _customers; private void UserControl_Loaded(object sender, RoutedEventArgs e) { if (!System.ComponentModel.DesignerProperties.GetIsInDesignMode(this)) { _wcfDataServicesEntities = new MyEntities(new Uri("http://localhost:7156/MyDataService.svc/")); _customersViewSource = this.Resources["customersViewSource"] as CollectionViewSource; DataServiceQuery<Customer> query = _wcfDataServicesEntities.Customer; query.BeginExecute(result => { _customers = new ObservableCollection<Customer>(); Array.ForEach(query.EndExecute(result).ToArray(), _customers.Add); Dispatcher.BeginInvoke(() => { _customersViewSource.Source = _customers; }); }, null); } } private void button1_Click(object sender, RoutedEventArgs e) { _wcfDataServicesEntities.BeginSaveChanges(r => { var response = _wcfDataServicesEntities.EndSaveChanges(r); string[] results = new[] { response.BatchStatusCode.ToString(), response.IsBatchResponse.ToString() }; _customers[0].FinAssistCompanyName = String.Join("|", results); }, null); } The response string I get back data binds to my grid OK and shows "-1|False". My intent is to get a proof-of-concept working here and then do the appropriate separation of concerns to turn this into a simple line-of-business app. I've spent hours and hours on this. I'm being driven insane. Any ideas how to get this working?

  • Combined SOAP/JSON/XML in WCF, using UriTemplate

    - by gregmac
    I'm trying to build a generic web service interface using WCF, to allow 3rd party developers to hook into our software. After much struggling and reading (this question helped a lot), I finally got SOAP, JSON and XML (POX) working together. To simplify, here's my code (to make this example simple, I'm not using interfaces -- I did try this both ways): <ServiceContract()> _ Public Class TestService Public Sub New() End Sub <OperationContract()> _ <WebGet()> _ Public Function GetDate() As DateTime Return Now End Function '<WebGet(UriTemplate:="getdateoffset/{numDays}")> _ <OperationContract()> _ Public Function GetDateOffset(ByVal numDays As Integer) As DateTime Return Now.AddDays(numDays) End Function End Class and the web.config code: <services> <service name="TestService" behaviorConfiguration="TestServiceBehavior"> <endpoint address="soap" binding="basicHttpBinding" contract="TestService"/> <endpoint address="json" binding="webHttpBinding" behaviorConfiguration="jsonBehavior" contract="TestService"/> <endpoint address="xml" binding="webHttpBinding" behaviorConfiguration="poxBehavior" contract="TestService"/> <endpoint address="mex" contract="IMetadataExchange" binding="mexHttpBinding" /> </service> </services> <behaviors> <endpointBehaviors> <behavior name="jsonBehavior"> <enableWebScript/> </behavior> <behavior name="poxBehavior"> <webHttp /> </behavior> </endpointBehaviors> <serviceBehaviors> <behavior name="TestServiceBehavior"> <serviceMetadata httpGetEnabled="true"/> <serviceDebug includeExceptionDetailInFaults="false"/> </behavior> </serviceBehaviors> </behaviors> This actually works -- I'm able to go to TestService.svc/xml/GetDate for xml, TestService.svc/json/GetDate for json, and point a SOAP client at TestService.svc?wsdl and have the SOAP queries work. The part I'd like to fix is the queries. I have to use TestService.svc/xml/GetDateOffset?numDays=4 instead of TestService.svc/xml/GetDateOffset/4. If I specify the UriTemplate, I get the error: Endpoints using 'UriTemplate' cannot be used with 'System.ServiceModel.Description.WebScriptEnablingBehavior'. But of course without using <enableWebScript/>, JSON doesn't work. The only other thing I've seen that I think will work is making 3 different services (.svc files), that all implement an interface that specifies the contract, but in the classes specify different WebGet/WebInvoke attributes on each class. This seems like a lot of extra work, that frankly, I don't see why the framework doesn't handle for me. The implementation of the classes would all be the same, except for the attributes, which means over time it would be easy for bugs/changes to get fixed/done in one implementation but not the others, leading to inconsistent behaviour when using the JSON vs SOAP implementation for example. Am I doing something wrong here? Am I taking a totally wrong approach and misusing WCF? Is there a better way to do this? With my experience doing web stuff, I think it should be possible for some kind of framework to handle this ... I even have an idea in my head of how to build it. It just seems like WCF is supposed to be doing this, and I don't really want to reinvent the wheel.

  • 'normal' SVC versus 'Silverlight' SVC (WCF)

    - by Michel
    Hi, i'm trying to call a WCF service from my Silverlight 3 app. But... when trying to create a 'silverlight enabled wcf service' in my web project, my VS2008 crashes during creating the item (i think while editing the web.config). So i thought: let's create a 'normal' wcf service, and manually edit it to be a 'silverlight enabled webservice'. So i wondered what the differences are, and second: why is there a difference between a service called from a silverlight app and a non-silverlight app?

  • Clickonce installation fails after addition of WCF service project

    - by Ant
    So I have a winform solution, deployed via clickonce. Eveything worked fine until i added a WCF project. (see error in parsing the manifest file at end of post) Now I notice that MSBuild compiles the service into a _PublishedWebsites dir. I don't know what the need for this is, but I am suspecting this is the cause of the problem. This wcf project references some other projects within the solution. I am actually hosting the wcf service within the application so I don't really need MSBuild to do all this for me.

  • WCF REST Question, Binding, Configuration

    - by Ethan McGee
    I am working on a WCF rest interface using json. I have wrapped the service in a windows service to host the service but I am now having trouble getting the service to be callable. I am not sure exactly what is wrong. The basic idea is that I want to host the service on a remote server so I want the service mapped to port localhost:7600 so that it can be invoked by posting data to [server_ip]:7600. The problem is most likely in the configuration file, since I am new to WCF and Rest I wasn't really sure what to type for the configuration so sorry if it's a total mess. I removed several chunks of code and comments to make it a little easier to read. These functions should have no bearing on the service since they call only C# functions.

  • WCF service using duplex channel in different domains

    - by ds1
    I have a WCF service and a Windows client. They communicate via a Duplex WCF channel which when I run from within a single network domain runs fine, but when I put the server on a separate network domain I get the following message in the WCF server trace... The message with to 'net.tcp://abc:8731/ActiveAreaService/mex/mex' cannot be processed at the receiver, due to an AddressFilter mismatch at the EndpointDispatcher. Check that the sender and receiver's EndpointAddresses agree. So, it looks like the communication just work in one direction (from client to server) if the components are in two separate domains. The Network domains are fully trusted, so I'm a little confused as to what else could cause this? Server app.config <?xml version="1.0" encoding="utf-8" ?> <configuration> <system.serviceModel> <behaviors> <serviceBehaviors> <behavior name="JobController.ActiveAreaBehavior"> <serviceMetadata httpGetEnabled="false" /> <serviceDebug includeExceptionDetailInFaults="true" /> </behavior> </serviceBehaviors> </behaviors> <services> <service behaviorConfiguration="JobController.ActiveAreaBehavior" name="JobController.ActiveAreaServer"> <endpoint address="mex" binding="mexTcpBinding" bindingConfiguration="" contract="IMetadataExchange" /> <host> <baseAddresses> <add baseAddress="net.tcp://SERVER:8731/ActiveAreaService/" /> </baseAddresses> </host> </service> </services> </system.serviceModel> </configuration> but I also add an end point programmatically in Visual C++ host = gcnew ServiceHost(ActiveAreaServer::typeid); NetTcpBinding^ binding = gcnew NetTcpBinding(); binding->MaxBufferSize = Int32::MaxValue; binding->MaxReceivedMessageSize = Int32::MaxValue; binding->ReceiveTimeout = TimeSpan::MaxValue; binding->Security->Mode = SecurityMode::Transport; binding->Security->Transport->ClientCredentialType = TcpClientCredentialType::Windows; ServiceEndpoint^ ep = host->AddServiceEndpoint(IActiveAreaServer::typeid, binding, String::Empty); // Use the base address Client app.config <?xml version="1.0" encoding="utf-8" ?> <configuration> <system.serviceModel> <bindings> <netTcpBinding> <binding name="NetTcpBinding_IActiveAreaServer" closeTimeout="00:01:00" openTimeout="00:01:00" receiveTimeout="00:10:00" sendTimeout="00:01:00" transactionFlow="false" transferMode="Buffered" transactionProtocol="OleTransactions" hostNameComparisonMode="StrongWildcard" listenBacklog="10" maxBufferPoolSize="524288" maxBufferSize="65536" maxConnections="10" maxReceivedMessageSize="65536"> <readerQuotas maxDepth="32" maxStringContentLength="8192" maxArrayLength="16384" maxBytesPerRead="4096" maxNameTableCharCount="16384" /> <reliableSession ordered="true" inactivityTimeout="00:10:00" enabled="false" /> <security mode="Transport"> <transport clientCredentialType="Windows" protectionLevel="EncryptAndSign" /> <message clientCredentialType="Windows" /> </security> </binding> </netTcpBinding> </bindings> <client> <endpoint address="net.tcp://SERVER:8731/ActiveAreaService/" binding="netTcpBinding" bindingConfiguration="NetTcpBinding_IActiveAreaServer" contract="ActiveArea.IActiveAreaServer" name="NetTcpBinding_IActiveAreaServer"> <identity> <userPrincipalName value="[email protected]" /> </identity> </endpoint> </client> </system.serviceModel> </configuration> Any help is appreciated!

  • Silverlight 4 with WCF RIA architecture applying DDD

    Hello, In my ASP.NET MVC applications I use DDD and it works very well. I'm new to Silverlight development and would like to know how could I apply DDD to build a new architecture. I had a look on WCF RIA Services and what is exposed by default it's the simple CRUD methods. I would like to use MVVM pattern. I thought about general architecture and don't know if what I'm thinking about make sense in Silverlight development. I thought about creating Domain Model on the top of SVC. I would than expose by WCF RIA some operation that deals with aggreates in my Domain Model instead of simple CRUD. What I would aloso expose is the ViewModel entieties that could be used by the view. I don't know if it's make sense, if I'm going in a good direction or if applying DDD in Silverlight 4 development is a good practice. I didn't find much informations on Internet. I'll appreciate if you could point me to some interesting links or if you can give me some hints. Thanks for your help.

  • Silverlight WCF netTcpBinding problem

    - by JontyMC
    Trying to call a WCF with a netTcpBinding via Silverlight, I am getting the error: "TCP error code 10013: An attempt was made to access a socket in a way forbidden by its access permissions.. This could be due to attempting to access a service in a cross-domain way while the service is not configured for cross-domain access. You may need to contact the owner of the service to expose a sockets cross-domain policy over HTTP and host the service in the allowed sockets port range 4502-4534." My WCF service is hosted in IIS7, bound to: http://localhost.myserivce.com on port 80 and net.tcp on port 4502 I can see http://localhost.myserivce.com/myservice.svc if I browse to it (my hosts file is pointing this domain to localhost). I can also see http://localhost.myserivce.com/clientaccesspolicy.xml: <?xml version="1.0" encoding="utf-8"?> <access-policy> <cross-domain-access> <policy> <allow-from http-request-headers="*"> <domain uri="*" /> </allow-from> <grant-to> <socket-resource port="4502-4534" protocol="tcp" /> </grant-to> </policy> </cross-domain-access> </access-policy> What am I doing wrong?

  • WCF Web Service Gives 404 error in Azure

    - by landyman
    I'm new to using WCF and Azure, but I have a WCF Web Service that works correctly when debugging in Visual Studio. I set the startup project to Azure, and I get 404 errors for any URL I try related to the service. Here is what I think is relavant code: From IWebService.cs [OperationContract] [WebGet(UriTemplate = "GetData/Xml?value={value}", ResponseFormat=WebMessageFormat.Xml)] string GetDataXml(string value); and from Web.config: <system.serviceModel> <services> <service name="WebService" behaviorConfiguration="WebServiceBehavior"> <!-- Service Endpoints --> <endpoint address="" binding="webHttpBinding" contract="IWebService" behaviorConfiguration="WebEndpointBehavior"></endpoint> <endpoint address="ws" binding="wsHttpBinding" contract="IWebService"/> <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange"/> </service> </services> <behaviors> <serviceBehaviors> <behavior name="WebServiceBehavior"> <serviceMetadata httpGetEnabled="true"/> <serviceDebug includeExceptionDetailInFaults="true"/> </behavior> </serviceBehaviors> <endpointBehaviors> <behavior name="WebEndpointBehavior"> <webHttp/> </behavior> </endpointBehaviors> </behaviors> </system.serviceModel> I have tried changing the binding to 'basicHttpBinding', but that had no luck. Thanks in advance for any help!

  • Question about using ServiceModelEx's "WCFLogbook" from "Programming WCF Services" book

    - by Bill
    I am attempting to compile/run a sample WCF application from Juval Lowy's website (author of Programming WCF Services & founder of IDesign). Of course the example application utilizes Juval's ServiceModelEx library and logs faults/errors to a "WCFLogbook" database. Unfortunately, when the sample app faults, I get the following new error: "Cannot open database "WCFLogbook" requested by the login. The login failed. Login failed for user 'Bill-PC\Bill'." I suspect the error occurs as a result of not finding the "WCFLogbook" database, which I believe still needs to be created. Included in the library source directory, there are two files -WCFLogbookDataSet.xsd and WCFLogbook.sql; which neither seem to be referenced anywhere within the library code. This leads me to beleive that the sql and xsd files are there to be used to create the database somehow in SQL. Could someone please advise me if I am going in the correct direction here and if whether these files can be used to create the database (and if so, how)?
