I have a WCF Client Proxy connected to a third party webservice. The proxy works fine with nearly everything except on function.
This function works just fine with a ASMX proxy.
I have added service trace logging and can see the response from the service coming back. Only the proxy returns null.
So now I know for sure that the proxy is at fault.
Where to from here?
RESOLUTION I found the issue. WCF is less forgiving than an ASMX proxy. The service WSDL specifies that the returned object was called "data", and the actual xml passed back was called "result"
So that was a great goose chase! I think i wasted 4 hours on this problem!
