c# - How do I prevent a WCF service from enter a faulted state?

Question

I have a WCF Service that should not enter the faulted state. If there's an exception, it should be logged and the service should continue uninterrupted. The service has a one-way operation contract and is reading messages from an MSMQ.

My problems are twofold:

1. The service appears to be swallowing an exception/fault so I am unable to debug it. How do I get the service to expose the exception so that I can log or handle it?
2. The service is entering into a faulted state after this exception is swallowed. How do I prevent the service from entering into a faulted state?

Answer 1

The official documentation on how to handle Faults is here:

• Handling Exceptions and Faults

• Understanding State Changes

with the main page being at Channel Model Overview

There's a nice state diagram showing how things happen:
