When coding against team foundation server you must be aware that some of the exceptions thrown by Team Foundation Server are not Serilisable! I think that this was an oversite by Microsoft, but it is there none the less.
An example of this is; TeamFoundationServerUnauthorizedException
If you want to handle this exception accross Windows Communication Foundation you will need to create a custom exception of the same name and re-throw this accross your services.
<DataContract()> _
Public Class TeamFoundationServerUnauthorizedException
Public Sub New()
…
End Sub
End Class
Make sure that you mark it as a data contract and then you can throw it when you encounter the Team Foundation Server exception:
Try
‘ Team Foundation Server Connection Code
Catch ex As TeamFoundationServerUnauthorizedException
Throw New FaultException(Of FaultContracts.TeamFoundationServerUnauthorizedException)(New FaultContracts.TeamFoundationServerUnauthorizedException())
Catch ex As System.Exception
Throw New FaultException(Of System.Exception)(ex, “Failed to do team server thing”, New FaultCode(“Team Foundation Server:EH:S:0001″))
End Try
This will allow you to handle Team Foundation Server exceptions for your Windows Communication Foundation service application on the client.
