Hi

I occasionally run into the problem that an application exception is thrown during the WCF-serialization (after returning a DataContract from my OperationContract). The only (and less meaningfull) message I get is

System.ServiceModel.CommunicationException : The underlying connection was closed: The connection was closed unexpectedly.

without any insight to the inner exception, which makes it really hard to find out what caused the error during serialization.

Does someone know a good way how you can trace, log and debug these exceptions? Or even better can I catch the exception, handle them and send a defined FaulMessage to the client?

thank you
