How to handle Transport and Communication level Exception in WCF?

Question

I know that we can use FaultException and FaultContract to catch these exception?

Is there any other way to (Except FaultException/FaultContract) catch specifically these two Exception (Transport and Communication)?

Answer 1

According to the Microsoft documentation, transport and communication errors are handled by the CommunicationException class.

Communication errors occur when a network is unavailable, a client uses an incorrect address, or the service host is not listening for incoming messages. Errors of this type are returned to the client as CommunicationException or CommunicationException-derived classes.

The following provides a good overview of the three categories of WCF errors:

• Communication Errors
• Proxy/Channel Errors
• Application Errors
