SL 2.0 Service model won't recognize FaultContractAttribute

04-04-2008 1:22 PM |

I have Silverlight 2.0 client consuming WCF service. The WCF Service is integrated with Validation Application Block of Enterprise library 3.1 (May 2007). The SL client has corresponding code to handle Fault exception returned by WCF. 
After adding the service reference to SL application and when i build the solution, i am getting compilation error:

The type or namespace name 'FaultContractAttribute' does not exist in the namespace 'System.ServiceModel' (are you missing an assembly reference?) C:\WCFValidationBlock\ClientSilverLight\Service References\ServiceAgent\Reference.cs 

After some investigation i found that the WCF service application has reference to System.ServiceModel.dll, which is of version 3.0.0.0 and SL application has its own set of assemblies and it works only with them. The System.ServiceModel.dll that SL application refers to is of version 2.0.5.0

When i try to manually change the assembly reference of SL application to 3.0.0.0 it throws an error message which says "You can't add a reference to System.ServiceModel.dll as it was not built against Silverlight runtime. Silverlight projects will only work with Silverlight assemblies".

Can anybody help me in resolving this and make the SL client application work along with WCF service (with Validation Application Block).

Any alternate solutions are welcome.

Thanks

Does that mean that if your WCF services have FaultContractAttribute specified, you cannot consume them in Silverlight?

All my service contracts are decorated with a faultContract tag:

[FaultContract(typeof(MyCustomFault))] 

 ...does this mean I STILL don't have any way of consuming these services in Silverlight BETA 1?

Are there any work-arounds for this (that don't involve editing the services)?
 

EDIT: I managed to make successful calls by doing the following:

Press the "Show all files" button.
Navigate to the References.cs file in the service reference.
Manually delete the FaultContract tags on the contract definition tags.

Obviously you can't handle the soap faults if the get thrown, but at least the the calls can be made.
