Throwing FaultException<T> from WCF service methods

Question

I am learning WCF, and currently focusing on the Faults chapter.

As i understand, WCF handles FaultException exceptions a bit differently when thrown by a service.

As such, it seems like a good idea that all exceptions that are thrown from a service should be wrapped into a FaultException.

Design wise it seems a bit counter-intuitive for me with respect to the design that WCF seems to favor (a clean separation between the actual logic and the "service" configuration/hosting/service-like details).

Is this a good practice then? or is there any other technique that should be used?

Answer 1

It is common practice to set up a FaultContract on your WCF service, which defines how it is has failed, and then handle this at the client side.
