Silverlight exception (faults) handling from wcf service


I want get exeption code from wcf method but i always get NotFound error.

Client Side:

public MainPage()
    {
        InitializeComponent();
        client.TestCompleted += new EventHandler<System.ComponentModel.AsyncCompletedEventArgs>(TestCompleted);
    }

    void TestCompleted(object sender, System.ComponentModel.AsyncCompletedEventArgs e)
    {
        if(e.Error!=null)
        {
            //HOW to get here my class BaseFault???
        }
    }

Server side:

[ServiceContract]
public interface IService1
{
    [OperationContract]
    [FaultContract(typeof(BaseFault))]
    void Test(int id);
}

  public void Test(int id)
  {
            try
            {
                if (id == -1)
                    ThrowEx(new BaseFault() { ErrorCode = ProcessErrorsCode.InvalidArgument });
                else
                    throw new NullReferenceException("some server error with null value");
            }
            catch
            {
                ThrowEx(new BaseFault() { ErrorCode = ProcessErrorsCode.InternalServerError });
            }
   }


 public void ThrowEx(BaseFault fault)
 {
    throw new FaultException<BaseFault>(fault);
 }



    [DataContract]
    public class BaseFault
    {
        [DataMember]
        public ProcessErrorsCode ErrorCode { get; set; }
    }

Config (includeExceptionDetailInFaults set to True):

<configuration>
    <system.web>
        <compilation debug="true" targetFramework="4.0" />
    </system.web>

    <system.serviceModel>
        <behaviors>
            <serviceBehaviors>
                <behavior name="">

                    <serviceMetadata httpGetEnabled="true" />
                    <serviceDebug includeExceptionDetailInFaults="True" />
                </behavior>
            </serviceBehaviors>
        </behaviors>
        <serviceHostingEnvironment multipleSiteBindingsEnabled="true" />
    </system.serviceModel>
</configuration>

I need to get BaseFault type on my client side. How to do that?


Solution

  • Found easy solution for me:

            bool registerResult = WebRequest.RegisterPrefix("http://", WebRequestCreator.ClientHttp);
    

    just add this line of code and it works without configuration.
