Service Contracts with Message causes duplicate proxy classes

Question

Hi,

I have a service contract with Message as shown below.

[OperationContract]
Message MyMethodWithMessage(Message myMsgParam);

Everything works fine. I could host my services. But when I try to create proxies through "Add Service References", I am getting the duplicate proxy classes. If I take out the above OperationContract and re run my services and try to create proxies, then "Add Service References" does not provide duplicate proxies. I am really confused about this!!!

Any help is greatly appreciated...

Thank you,

Suresh
