Catching Faults from Dynamics AX 2012 WCF services

I hit problems in an orchestration consuming WCF services exposed by Microsoft Dynamics AX 2012 (AX6). When attempting to catch a fault response, I was getting the error "received unexpected message type 'http://www.w3.org/2003/05/soap-envelope#fault'"

In order to fix this, I needed to change the schema for the fault message in the port type that had been created using "Add Generated Items." I changed it to the SOAP 1.2 fault type.

Thanks to this blog for pointing me in this direction:
