Remarks

Robust client Silverlight applications handle CommunicationException objects that may be thrown during communication. There is also a CommunicationException derived exception type, FaultException, that clients also often expect. Therefore, to prevent the generic CommunicationException handler from catching this more specific exception types, catch this exception prior to handling CommunicationException.

FaultException objects are thrown when a listener receives a SOAP fault that is not expected or specified in the operation contract.
