• How can I add a prefix to a WCF ServiceContract Namespace

  - by Lodewijk

  Hi, I'm trying to implement an UPnP MediaServer in WCF. I'm slowly getting there, but now I've hit a brick wall. I need to add a prefix to the ServiceContract namespace. Right now I have the following: [ServiceContract(Namespace = "urn:schemas-upnp-org:service:ContentDirectory:1")] public interface IContentDirectory { [OperationContract(Action = "urn:schemas-upnp-org:service:ContentDirectory:1#Browse")] void Browse(string ObjectID, string BrowseFlag, string Filter, ulong StartingIndex, ulong RequestedCount, string SortCriteria, out string Result, out ulong NumberReturned, out ulong TotalMatches, out ulong UpdateID); } This listens to the correct soap-messages. However, I need the soap-body to begin with <u:Browse xmlns-u="urn:schemas-upnp-org:service:ContentDirectory:1"> and WCF is now listening to: <Browse xmlns="urn:schemas-upnp-org:service:ContentDirectory:1"> How do I get the prefix there? Does it matter? Or is there another reason why the parameters are not passed into the Browse method?

• WCF RIA Services build error

  - by soren.enemaerke

  Hi I'm getting a strange error when building my WCF RIA Services Silverlight project in VS2008. In the output I have this message: C:\Program Files\MSBuild\Microsoft\Silverlight\v3.0\Microsoft.Ria.Client.targets(261,5): error : Failed to write the generated contents of 'C:\projects\[Path_To_Silverlight_Project]\Generated_Code\Analytics.Web.g.cs' to Visual Studio. ...and Visual Studio opens a dialog while building with the following: An editor or project is attempting to save a file that is modified in memory. Saving files during a build is dangerous and may result in incorrect build outputs in the future. Continue with save? The other members on my team seems to be doing just fine, but I can't get past this point (I can if I click 'Continue' which then generate the file just fine but I'm reluclant to do so). There must be some setup or similar that I'm missing here... PS: I'm currently on WinXP and WCF RIA Service beta

• TimeoutException in simultaneous calls to WCF services from Silverlight application

  - by Alexander K.

  Analysing log files I've noticed that ~1% of service calls ended with TimeoutException on the Silverlight client side. The services (wcf) are quite simple and do not perform long computations. According the log all calls to the services are always processed in less that 1 sec (even when TimeoutException is occurred on the client!), so it is not server timeout. So what is wrong? Can it be configuration or network problem? How can I avoid it? What additional logging information can be helpful for localizing this issue? The only one workaround I've thought up is to retry service calls after timeout. I will appreciate any help on this issue! Update: On startup the application performs 17 service calls and 12 of them simultaneously (may it be cause of failure?). Update: WCF log has not contained useful information about this issue. It seems some service calls do not reach the server side.

• Entity Framework and consuming a WCF service

  - by nakori

  I'm getting data where the database is hidden behind a WCF service. Is it possible to use Entity Framework in a scenario where I have custom objects coming from a web service? (No access to the external database, and no current plans for insert/update/delete logic) Starting with an empty EF model and adding an entity I get this error on compile: No mapping specified for instances of the EntitySet and AssociationSet in the EntityContainer .. Is it possible to make an entity this way, and fill it with data received from an object? (In this case a WCF, but could also be a predefined model class/xml data) If the web service retured a Customer object I could do something like this with a dataset: Make an unbound table and do a loop through the customer properties adding them to a temp row, add it with tbl_Customer.Addtbl_CustomerRow(customerRow) to get my view filled. thanks, nakori

• Config for WCF with multiple endpoints

  - by vdh_ant

  Hi guys I'm new to WCF and am trying to get some ideas I have off the ground. Basically I have a web WCF Application project with the following in its web.config: <system.serviceModel> <services> <service name="WcfService1.ServiceContract.IDirectorySearchService" behaviorConfiguration="defaultServiceBehavior"> <endpoint name="restxml" address="xml" binding="webHttpBinding" contract="WcfService1.ServiceContract.IDirectorySearchServiceXml" behaviorConfiguration="xmlRestBehavior"/> <endpoint name="restjson" address="json" binding="webHttpBinding" contract="WcfService1.ServiceContract.IDirectorySearchServiceJson" behaviorConfiguration="jsonRestBehavior"/> <endpoint name="soap" address="soap" binding="basicHttpBinding" contract="WcfService1.ServiceContract.IDirectorySearchService"/> <endpoint name="mex" address="mex" binding="mexHttpBinding" contract="IMetadataExchange"/> </service> </services> <behaviors> <serviceBehaviors> <behavior name="defaultServiceBehavior"> <serviceDebug includeExceptionDetailInFaults="true"/> </behavior> </serviceBehaviors> <endpointBehaviors> <behavior name="xmlRestBehavior"> <webHttp/> </behavior> <behavior name="jsonRestBehavior"> <enableWebScript/> </behavior> </endpointBehaviors> </behaviors> </system.serviceModel> My interfaces look like this: [ServiceContract] public interface IDirectorySearchServiceXml { [OperationContract] [WebGet(UriTemplate = "Search/")] SearchResults Search(); } [ServiceContract] public interface IDirectorySearchServiceJson { [OperationContract] [WebGet(UriTemplate = "Search/")] SearchResults Search(); } [ServiceContract] public interface IDirectorySearchService { [OperationContract] SearchResults Search(int? sportId, int? instituteId, DateTime? startDate, DateTime? endDate); } Now the part I am having a little trouble with is what else I need to get this up and running... Like given this what .svc files do I need and do I have the config right... Also what addresses do I need to use to get this running either through the browser or through the WCF test client. Note I am currently using 3.5. Cheers Anthony

• Win CE 6.0 client using WCF Services

  - by Sean

  We have a Win CE 6.0 device that is required to consume services that will be provided using WCF. We are attempting to reduce bandwidth usage as much as possible and with a simple test we have found that using UDP instead of HTTP saved significant data usage. I understand there are limitations regarding WCF on .NET Compact Framework 3.5 devices and was curious what people thought would be the appropriate way forward. Would it make sense to develop a custom UDP binding, and would that work for both sides? Any feedback would be appreciated. Thanks.

• WCF performance improvements

  - by Burt

  I am developing a WPF application that talks to a server via WCF services over the internet. After profiling the application I noticed a lot of time is being taking up by creating the appropriate WCF client proxy and making the call to the server. The code on the server is optimised and doesn't take any time to run yet I am still seeing a 1.5 second delay from when a service is invloked to it returning to the client. A few points to give a bit of background: I am using the ASP.Net membership for security I will eventually hook into the same server side code through a website I would eventually like to have offline support in the application I really need to nail the performance early though as if the app is taking a couple of seconds to come back it is too long for what I am trying to do. Can anyone suggest performance tips that will help me please?

• HTTP 404 Error manifests itself as EndPointNotFoundException on a WCF client

  - by dudia

  How can I make my client treat 404 Error correctly? Right now it catches a general exception... My WCF Server uses WebOperationContext.Current.OutgoingResponse.SetStatusAsNotFound(); To return a 404 Error code however my WCF client interperts it as an EndPointNotFoundException There was no endpoint listening at http://myUrl that could accept the message. This is often caused by an incorrect address or SOAP action. See InnerException, if present, for more details. The inner exception is WebException "The remote server returned an error: (404) Not Found.

• Only send populated object properties over WCF?

  - by dlanod

  I have an object that is being sent across WCF that is essentially a property holder - it can potentially have a large number of properties, i.e. up to 100, but in general only a small subset will be set, up to 10 for instance. Example: [DataContract(Namespace = "...")] public class Monkey { [DataMember] public string Arms { get; set; } [DataMember] public string Legs { get; set; } [DataMember] public string Heads { get; set; } [DataMember] public string Feet { get; set; } [DataMember] public string Bodies { get; set; } /* repeat another X times */ } Is there a way to tell WCF to only send the populated properties over the wire? It seems like a potential waste of bandwidth to send over the full object.

• IIS7 + WCF + Silverlight problems

  - by Eanna

  Hey, I've been building a silverlight application and a WCF service for a while now and recently tried to host them in IIS7. I installed IIS7 on Windows Server 2008 R2 and added these two application to my default website. I am having a number of problems so im hoping one of you can help out... 1) The silverlight and WCF service applications do not work with pass-through authentication. I need to "connect as" the administrator server account when setting up the application. I read online that you should only need to use the "connect as" field when you are connecting to another computer. If i dont supply the admin credentials i get this error. Do i have to set up permissions somewhere else? HTTP Error 500.19 - Internal Server Error The requested page cannot be accessed because the related configuration data for the page is invalid. Detailed Error Information Module IIS Web Core Notification BeginRequest Handler Not yet determined Error Code 0x80070005 Config Error Cannot read configuration file due to insufficient permissions Config File \?\C:\Users\Administrator\Documents\My Dropbox\Research Masters\Project\WCFService\Website\web.config Requested URL http:://localhost:80/WCFService/Service.svc Physical Path C:\Users\Administrator\Documents\My Dropbox\Research Masters\Project\WCFService\Website\Service.svc Logon Method Not yet determined Logon User Not yet determined Config Source -1: 0: Links and More Information This error occurs when there is a problem reading the configuration file for the Web server or Web application. In some cases, the event logs may contain more information about what caused this error. 2) Visual studio generated 2 webpages to run my silverlight application (.html and .aspx). When I am running the silverlight application (connected as admin) I can navigate to the .html page, no problem. When I try to open the .aspx file i get the following error Server Error in '/Platform' Application. Access is denied. Description: An error occurred while accessing the resources required to serve this request. You might not have permission to view the requested resources. Error message 401.3: You do not have permission to view this directory or page using the credentials you supplied (access denied due to Access Control Lists).

Version Information: Microsoft .NET Framework Version:4.0.30128; ASP.NET Version:4.0.30128.1 3) The WCF service runs fine (again, connected as admin) until i restart the server. When i try to run the WCF service after a reboot, the mysql assembly seems to be missing from the solution. If i just rebuilt the solution and run the service again... it works (until next restart).

• WCF MessageContract Help - MessageBodyMember with hyphenated name

  - by Hcabnettek

  Hi All, I need a bit of WCF help. This project uses message contracts. The transport seems to work ok. I have this code for a response type. namespace tpoke.Contracts { [MessageContract(IsWrapped = true)] public class AuthenticationResponseMC { [MessageBodyMember(Name = "authentication-token")] public Guid AuthenticationToken; } } Now when I run the operation that returns this, I try to deserialize using the XmlSerializer. The is not what I'm needing. I need it to be <authentication-token xmlns="http://tpoke.wcf.com">e13xxxx-xxxx-xxxx-xxxxxx</authentication-token> How can I make this work correctly? Do I need to add the namespace to MessageBodyMember? Why is the hyphen being stripped out? Any tips or advice is certainly appreciated. Thanks, ~ck in San Diego

• ASP.NET / WCF - Execute Server.Execute Asynchronously

  - by user208662

  Hello, I need to run the HttpContext.Current.Server.Execute method in my ASP.NET application. This application has a WCF operation that does some processing. Currently, I am to do my processing correctly from within my WCF operation. However, I would like to do this asynchronously. In an error to attempt this asynchronously, I tried running Server.Execute in the DoWork event handler of a BackgroundWorker. Unfortunately, this throws an error that says "object reference not set to an instance of an object" The HttpContext element is not null. I checked that. It is some property nested in the HttpContext object that appears to be null. However, I have not been able to identify why this won't work. It happens as soon as I move the processing to the BackgroundWorker thread. My question is, how can I asynchronously execute the Server.Execute method? Thank you,

• How to make dynamically generated .net service client read configuration from another location than

  - by Bryan

  Hi, I've currently written code to use the ServiceContractGenerator to generate web service client code based on a wsdl, and then compile it into an assembly in memory using the code dom. I'm then using reflection to set up the binding, endpoint, service values/types, and then ultimately invoke the web service method based on xml configuration that can be altered at run time. This all currently works fine. However, the problem I'm currently running into, is that I'm hitting several exotic web services that require lots of custom binding/security settings. This is forcing me to add more and more configuration into my custom xml configurations, as well as the corresponding updates to my code to interpret and set those binding/security settings in code. Ultimately, this makes adding these 'exotic' services slower, and I can see myself eventually reimplementing the 'system.serviceModel' section of the web or app.config file, which is never a good thing. My question is, and this is where my lack of experience .net and C# shows, is there a way to define the configuration normally found in the web.config or app.config 'system.serviceModel' section somewhere else, and at run time supply this to configuration to the web service client? Is there a way to attach an app.config directly to an assembly as a resource or any other way to supply this configuration to the client? Basically, I'd like attach an app.config only containing a 'system.serviceModel' to the assembly containing a web service client so that it can use its configuration. This way I wouldn't need to handle every configuration under the sun, I could let .net do it for me. Fyi, it's not an option for me to put the configuration for every service in the app.config for the running application. Any help would be greatly appreciated. Thanks in advance! Bryan

• WCF webservice stop working after upgrade to framework 3.5 sp1

  I have a wcf webservice on one of my testing servers. Everything worked fine until I upgraded frome framework 3.5 to 3.5 sp1. the wcf web service stoped working and returns the error: "Failed to invoke the service.

• Silverlight 4 accessing WCF Data Services: BeginInvoke frustrations.

  - by Gatmando

  Hi, I'm attempting to follow a pattern for performing WCF data service queries using the Silverlight 4 beta. The following is my code: public CodeTables() { CodeCountries = new ObservableCollection<dsRealHomes.CodeCountries>(); dsRealHomes.RealHomesEntities myClient = null; myClient = staticGlobals.RealHomesContext(); object userState = null; myClient.BeginExecute<dsRealHomes.CodeCountries>(new Uri("CodeCountries"), (IAsyncResult asyncResult) => { Dispatcher.BeginInvoke( () => { var test = myClient.EndExecute<dsRealHomes.CodeCountries>asyncResult).ToList(); } ); }, userState); } This is derived from a number of examples I've come across for WCF data services with silverlight. Unfortunately no matter how I try to implement the code i end up with the following error on 'Dispatcher.BeginInvoke': 'An object reference is required for the non-static field, method, or property (System.Windows.Threading.Dispatcher.BeginInvoke(System.Action)' Thanks

• Sanitizing incoming XML via WCF

  - by Clark

  I am consuming a Java webservice from .net using WCF. I am getting an error on deserialization of a response from the Java service The byte 0x00 is not valid at this location. Line 1, position 725. I know from some research that this is an incorrectly encoded null, but I am unlikely to get the provider to change it, so I would like to sanitize the null out before WCF deserializes the return message. Any Ideas? I am using c#, but answers in any CLR language will do.

• HTTP 400 Bad Request error attempting to add web reference to WCF Service

  - by c152driver

  I have been trying to port a legacy WSE 3 web service to WCF. Since maintaining backwards compatibility with WSE 3 clients is the goal, I've followed the guidance in this article. After much trial and error, I can call the WCF service from my WSE 3 client. However, I am unable to add or update a web reference to this service from Visual Studio 2005 (with WSE 3 installed). The response is "The request failed with HTTP status 400: Bad Request". I get the same error trying to generate the proxy using the wsewsdl3 utility. I can add a Service Reference using VS 2008. Any solutions or troubleshooting suggestions? Here are the relevant sections from the config file for my WCF service. <system.serviceModel> <services> <service behaviorConfiguration="MyBehavior" name="MyService"> <endpoint address="" binding="customBinding" bindingConfiguration="wseBinding" contract="IMyService" /> <endpoint address="mex" binding="mexHttpsBinding" contract="IMetadataExchange" /> </service> </services> <bindings> <customBinding> <binding name="wseBinding"> <security authenticationMode="UserNameOverTransport" /> <mtomMessageEncoding messageVersion="Soap11WSAddressingAugust2004" /> <httpsTransport/> </binding> </customBinding> </bindings> <behaviors> <serviceBehaviors> <behavior name="MyBehavior"> <serviceMetadata httpGetEnabled="true" /> <serviceDebug includeExceptionDetailInFaults="true" /> <serviceCredentials> <userNameAuthentication userNamePasswordValidationMode="Custom" customUserNamePasswordValidatorType="MyCustomValidator" /> </serviceCredentials> <serviceAuthorization principalPermissionMode="UseAspNetRoles" roleProviderName="MyRoleProvider" /> </behavior> </serviceBehaviors> </behaviors> <serviceHostingEnvironment aspNetCompatibilityEnabled="true" /> </system.serviceModel>

• What is a good pattern for binding a collection of objects coming from WCF, in Silverlight?

  - by Krishna

  Hi there, I've got a question about a Silverlight WCF Databinding pattern: There are many examples about how to bind data using {Binding} expressions in XAML, how to make async calls to a WCF service, set the DataContext property of a element in the UI, how to use ObservableCollections and INotifyPropertyChanged, INotifyCollectionChanged and so on. Background: I'm using the MVVM pattern, and have a Silverlight ItemsControl, whose ItemsSource is set to an ObservableCollection property on my ViewModel object. My view is of course the XAML which has the {Binding}. Say the model object is called 'Metric'. My ViewModel periodically makes calls to a WCF service that returns ObservableCollection. MetricInfo is the data transfer object (DTO). My question is two-fold: Is there any way to avoid copying each property of MetricInfo to the model class - Metric? When the WCF calls completes, is there any way to make sure I sync the items which are in both my local ObservableCollection and the result of the WCF call - without having to first clear out all the items in the local collection and then add all the ones from the WCF call result? thanks, Krishna

• Publishing WCF .NET 3.5 to IIS 6 (Windows Server 2003)

  - by Adam

  I've been developing a WCF web service using .NET 3.5 with IIS7 and it works perfectly on my local computer. I tried publishing it to a server running IIS 6 and even though I can view the WSDL in my browser, the client application doesn't seem to be connecting to it correctly. I launched a packet sniffing app (Charles Proxy) and the response for the first message comes back to the client empty (0 bytes). Every message after the first one times out. The WCF service is part of a larger application that uses ASP .NET 3.5. That application has been working fine on IIS 6 for awhile now so I think it's something specific to WCF. I also tried throwing an exception in the SVC file to see if it made it that far and the exception never got thrown so I have a feeling it's something more low level that's not working. Any thoughts? Is there anything I need to install on the IIS5 server? If so how am I still able to view the WSDL in my browser? The service is being consumed via an SVC file using basicHttpBinding Here's the meat of the Web.Config (let me know if you need any other part of it): <system.net> <defaultProxy> <proxy usesystemdefault="False" proxyaddress="http://127.0.0.1:80" bypassonlocal="True"/> </defaultProxy> </system.net> ... <system.serviceModel> <services> <service name="Nexternal.Service.XMLTools.VNService" behaviorConfiguration="VNServiceBehavior"> <!--The first endpoint would be picked up from the confirg this shows how the config can be overriden with the service host--> <endpoint address="" binding="basicHttpBinding" contract="Nexternal.Service.XMLTools.IVNService" /> <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" name="mexHttpBinding" /> </service> </services> <behaviors> <serviceBehaviors> <behavior name="VNServiceBehavior"> <serviceMetadata httpGetEnabled="true" /> <serviceDebug includeExceptionDetailInFaults="true" /> </behavior> </serviceBehaviors> </behaviors> <serviceHostingEnvironment aspNetCompatibilityEnabled="true" /> </system.serviceModel>

• WCF: Use a Message Contract to make a Soap Header

  - by Vaccano

  I need to add a soap header to my web service. I plan to use this to validate my clients (Windows Mobile Devices). I found this link: http://www.c-sharpcorner.com/UploadFile/rog_21/soapheaders05172007120046PM/soapheaders.aspx Which is exactly what I want to do. But it is not written for WCF. I have done some research and I seem to be paralyzed by the number of options. I basically want to add a simple header to my soap object that will be a user name and password. The client does not use WCF, so the soap header needs to just be a normal soap header. Any Sample code or shoves in the right direction would be appreciated.

  Hello there, I have two Services called TemplateService, TemplateReportService (both defined in one WCF Service Library) to be exposed to the client application. And, I am trying to host these services under Windows Service. Can anyone please guide me if App.config in Windows Service will be same as the one in WCF Library?
