In Visual Studio .NET, I try to generate C# proxy class from WSDL, and
the WSDL file has <wsdl:fault> element. I expect the generated proxy
code should have the exception code that corresponds to <wsdl:fault>
element, but it doesn't have any.

I did some research and found out WSDL description generated by a .NET
Web service does not contain any wsdl:fault or soapbind:fault elements.
I am not sure if this is true, and not sure if VS.NET supports
exception code generation from <wsdl:fault> element. Is that true?

any ideas? please advise.

thanks!!
