  • Why values in my WCF data contract were suddenly wrong...

    - by mipsen
    A WCF Service I provided took a very simple data contract as parameter (containing one string and one int...) and had a very simple task to do. A .NET 3.5 client was created using the VS2008 feature "Add Service Reference". Everything worked as expected. Then a slight change came in: The client was expected to run on machines with .NET 2.0 only. So we set the Target  Framework to .NET 2.0, removed the references to System.ServiceModel, System.Runtime.Serialization and the ServiceReference and created a new Reference to the Service using the old "Add Web Reference" . A matter of 2 minutes.  When testing, the int value in the data contract arriving at the WCF Service suddenly was 0, instead of 38 as we expected. What happened? When generating an old  Web Reference on a WCF data contract an additional boolean field for each value-type field is created called [Fieldname]Specified (e.g. AgeSpecified) which defaults to "false". WCF inspects these boolean fields to determine if a value was provided for the value-type field. If the "Specified"-field is "false", WCF translates that to using the default-value of the value-type field. For int this is 0. So we had to insert  setting the "Specified"-field  for the int-value to "true" and everything was fine again. That was what we forgot after setting the Framework-version to 2.0...

  • Liquid XML 2012 Service Pack 1 available

    - by bconlon
    Liquid XML Editor is one of my favourite tools, but I was slightly concerned with the original 2012 release as the new XML Data Mapper tool was a bit buggy. So I was pleased to see SP1 is now available for download.Sure enough the issues have been fixed and it's once more a great tool!The data mapper can also now be run from the command line (this was a little limiting before as you had to open the IDE to run the mapping) and the Help now contains full documentation.#

  • Google Analytics: Custom variables issue difference in data

    - by Bart
    We’ve set up tracking through custom variables in Google Analytics to measure which offices are getting the most traffic. The custom var consists out of the key (=office) and value = (office name). In our Custom Var tab in audience we get no data (actually we got 1 hit, but we think the data is way off). When we setup advanced segments with the filters on key and value we get the correct data. Now we are wondering why we aren’t getting that data in the custom var tab.

  • Unity LifeTimeManager for WCF

    I really love DI-frameworks. One reason is that it allows me to centralize life-time management of objects and services needed by others. Most frameworks have options to control the lifetime and allows objects to be created as Singletons, ThreadStatics, Transients (a new object everytime) etc. Im currently doing some work on a project where Unity [...]...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors?

  • MVVM and service pattern

    - by alfa-alfa
    I'm building a WPF application using the MVVM pattern. Right now, my viewmodels calls the service layer to retrieve models (how is not relevant to the viewmodel) and convert them to viewmodels. I'm using constructor injection to pass the service required to the viewmodel. It's easily testable and works well for viewmodels with few dependencies, but as soon as I try to create viewModels for complex models, I have a constructor with a LOT of services injected in it (one to retrieve each dependencies and a list of all available values to bind to an itemsSource for example). I'm wondering how to handle multiple services like that and still have a viewmodel that I can unit test easily. I'm thinking of a few solutions: Creating a services singleton (IServices) containing all the available services as interfaces. Example: Services.Current.XXXService.Retrieve(), Services.Current.YYYService.Retrieve(). That way, I don't have a huge constructor with a ton of services parameters in them. Creating a facade for the services used by the viewModel and passing this object in the ctor of my viewmodel. But then, I'll have to create a facade for each of my complexe viewmodels, and it might be a bit much... What do you think is the "right" way to implement this kind of architecture ?

  • Cross Domain access of self hosted WCF services?

    - by Macnique
    I have developed a WPF application which communicates with a set of self hosted WCF services which are under same domain and I use the following setup in the config files. <security mode="Transport"> <transport clientCredentialType="Windows" protectionLevel="EncryptAndSign" /> <message clientCredentialType="Windows" /> </security> I hosted the services on a server in different domain .I can achieve the communication by setting the security mode to "None" which is not ideal. Is there any other setting i can user for cross domain communication or i have to do with some trusted certificates ? I would be glad if some one can guide me because all the searches on google directed me to silverlight applications +Crossdomain.xml+WCF but i have't seen any combination of WPF on crossdomain environment.

  • Azure - Microsoft.IdentityModel not found

    - by Andy
    Hi There, I'm working with a WCF service in Azure, which uses Windows Live ID authentication with the recent deviceid requirements. When I host my WCF service locally in the compute emulator, it works properly, but when I deploy the cloud service to Azure and call it the same way (from another project that uses the WCF service as a service reference), I get the error: Could not load file or assembly 'Microsoft.IdentityModel, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The system cannot find the file specified. I found this post : http://social.msdn.microsoft.com/Forums/en-US/netservices/thread/cd139b5c-ad12-4298-af2f-1b2d0136a977 But there are a few problems: 1. I don't seem to have access to Microsoft.IdentityModel, only System.IdentityModel. I'm not sure why it's searching for something in 3.5 at all, as I'm building in .NET 4.0. 2. When I choose to "copy to local" on System.IdentityModel, it doesn't change anything. Any help? I would appreciate it! Best Regards, Andy

  • Parameter passing become pointer for integer

    - by Kangkan
    I am working on a c/Linux app for a device. I consume a web service (in WCF/c#) and use gSOAP for the same. The issue is that the parameters in the service methods become pointers for simple data types like int, short etc also. I initially used the same service exposed as ASMX web service and the client proxy generated using gSOAP created methods with parameters passed as values. But once the service has been upgraded to WCF, all the parameters became pointers. Can somebody help?

My web service has a method which return generic list and in my client application I use Configuration Service Reference to change array to generic list.Its working correctly.

  • Specify Windows Service Name on install with Setup Project

    - by sympatric greg
    Objective: In support of a Windows Service that may have multiple instances on a single machine, use a Setup Project to create an MSI capable of: Receiving user input for Service Name Installing service Serializing Service Name from 1 (so that the proper name can be used in logging and uninstall) My initial hope was to set Service Name in App.config (and then retrieve it during uninstall upon instantiation of the ServiceInstaller. This seems to have been naive, because it is not accessible during the install. If MyInstaller extends Installer, it can call base.Install(); however, my attempts to write to app.config (within MyInstaller.Install() and after base.Install()) are inneffective. So while the service can be installed with a custom Service Name, that name is not serialized and the installer is most displeased upon uninstall. How should this be done?

  • How to get a service to listen on port 80 on Windows Server 2003

    - by Miky D
    I've coded a custom windows service that listens on TCP port 80 but when I try to install it on a Windows Server 2003 machine it fails to start because some other service is already listening on that port. So far I've disabled the IIS Admin service and the HTTP SSL service but no luck. When I run netstat -a -n -o | findstr 0.0:80 it gives me the process id 4 as the culprit, but when I look at the running processes that process id points to the "System" process. What can I do to get the System process to stop listening on port 80 and get my service to listen instead? P.S. I should point out that the service runs fine if I install it on my Windows XP or Windows 7 development boxes. Also, I should specify that this has nothing to do with it being a service. I've tried starting a regular application that attempts to bing to port 80 on the Windows Server 2003 with the same outcome - it fails because another application is already bound to that port.
