title: BizTalk - Catch EndPoint Not found Exception
body: <p>The WCF service to which my send &amp; receive ports are configured, is not available; thus I am getting an EndPoint not found exception. How do I catch this exception in the middle of my orcehstration and flow towards a clean exit from the orchestration? I should be able to capture the detail and invoke a class lib (through Expression shape).</p>
  
  <p>I tried catching the FaultContract, System.Exception in the scope from which I am sending the request to port. But in vain.</p>
