I understand that WCF will convert an exception into a fault and send it back as a SOAP message, but I was wondering if this is truly interoperable. I guess I'm having a tough time trying to figure out this possible scenario:
- Client (Java) calls a WCF Service (LoginService).
- Server checks for proper authorization, user authorization fails.
- Server throws an UnauthorizedAccessException.
- WCF converts this into a Fault somehow. (* - See Below As Well)
- Client has to be able to know how to read this Fault.
I guess I'm just having a tough time understanding how this could still be interoperable because it is expecting Java to know how to translate a SOAP Fault that .NET encodes from an UnauthorizedAccessException.
- Also, how does .NET actually convert the exception to a fault, what goes in as the fault code, name, etc. Some of the things seem to be "duh"s like perhaps the Fault Name is "UnauthorizedAccessException", but I'd rather know for sure than guess.
