I\'m attempting to extend this answer on SO to make a WCF client retry on transient network failures and handle other situations that require a retry such as authentication
we have a WCF client that deal with almost any type of failure at the server. The Catch list is very long but does not have to be. If you look closely, you will see that many exceptions are child definitions of the Exception Class (and a few other classes).
Thus you can simplify things a lot if you want to. That said, here are some typical errors that we catch:
Server timeout
Server too busy
Server unavailable.
