Net Framework 3.0 Web service

Question

Hi,
We have created a webservice to read the COMPort of a local machine and hosted the same on the local machine. I have imported the WSDL file in ABAP as client proxy and also configured the logical port. On running the test with correct data, I am getting the following error.
Any hints will be a great help.
Regards,

  <ERRORTEXT>The message with Action '' cannot be processed at the receiver, due to a ContractFilter mismatch at the EndpointDispatcher. This may be because of either a contract mismatch (mismatched Actions between sender and receiver) or a binding/security mismatch between the sender and the receiver. Check that sender and receiver have the same contract and the same binding (including security requirements, e.g. Message, Transport, None).</ERRORTEXT>

Problem resolved. With the import of WSDL files generated using WCF and CTP framework SOAP action is set to Null in LPCONFIG. Once we put the correct SOAP action everything works fine.
