WCF Webservices and FaultContract - Client’s receiving SoapExc insted of FaultException

Question

Hi All,

i'm developing a WCF Webservice and consuming it within a mvc2 application. My problem is that i'm using FaultContracts on my methods with a custom FaultDetail and i'm throwing manyally the faultexception but when the client receive the exception , it receives a normal SoapException instead of my FaultException that i throwed from the service side.

Here is some code:

Custom Fault Detail Class:

 [DataContract]
public class MyFaultDetails
{
[DataMember]
public string Message { get; set; }
}

Operation on service contract:

 [OperationContract]
[FaultContract(typeof(MyFaultDetails))]
void ThrowException();

Implementation:

 public void ThrowException()
{
var details = new MyFaultDetails { Message = "Exception Test" };
throw new FaultException(details , new FaultReason(details .Message), new FaultCode("MyFault"));
}

Client side:
 
try
{
// Obv proxy init etc..
service.ThrowException();
}
catch (FaultException ex)
{
// stuff
}
catch (Exception ex)
{
// stuff
}

What i expect is to catch the FaultException , instead that catch is skipped and the next catch is taken with an exception of type SoapException.

Am i missing something ?

i red a lot of threads about using faultcontracts within wcf and what i did seems to be good. I had a look at the wsdl and xsd generated and they look fine. here's a snippet regarding this method:

 <wsdl:operation name="ThrowException">
      <wsdl:input wsaw:Action="http://tempuri.org/IAnyJobService/ThrowException" message="tns:IAnyJobService_ThrowException_InputMessage" />
      <wsdl:output wsaw:Action="http://tempuri.org/IAnyJobService/ThrowExceptionResponse" message="tns:IAnyJobService_ThrowException_OutputMessage" />
      <wsdl:fault wsaw:Action="http://tempuri.org/IAnyJobService/ThrowExceptionMyFaultDetails" name="MyFaultDetails" message="tns:IAnyJobService_ThrowException_MyFaultDetails_FaultMessage" />
    </wsdl:operation>

<wsdl:operation name="ThrowException">
      <soap:operation soapAction="http://tempuri.org/IAnyJobService/ThrowException" style="document" />
      <wsdl:input>
        <soap:body use="literal" />
      </wsdl:input>
      <wsdl:output>
        <soap:body use="literal" />
      </wsdl:output>
      <wsdl:fault name="MyFaultDetails">
        <soap:fault use="literal" name="MyFaultDetails" namespace="" />
      </wsdl:fault>
    </wsdl:operation>

Any help ?

Thanks in advance
