Not sure if I correctly understood your answer, so correct me if I'm wrong.

You can create a class library with your DataContracts classes and share the library between the client and server. In this way class marked [DataContract] will have methods (behavior) and [DataMember] fields/properties (state).

When you will pass such objects between client and server via WCF state will be persisted, but since class library is shared you will have methods on both sides.
