Windows Communication Foundation - Gotchas

Gotcha: Server is always receiving a NULL value parameter though the client is sending the appropriate data. Method signature in the proxy and wsdls seem to be correct.

Solution: Look for the name of the parameter in the generated wsdls. WCF does a string comparison of the parameters, therefore, watch out to see if the wsdls and the generated proxies have an exact match even in the parameter names. A trained programmer mind might often overlook this fact since in the world of computer programming method signatures matter and the actual parameter names are irrelevant.
