What I read from your question is, that you want to use interfaces as parameters or return types in a webmethod of a webservice.

If that is right, then you are out of luck. You can only use serializable types as parameters in a webmethod. When calling a webmethod, all parameters are serialized, transmitted and then deserialized at the receiving end. Deserializing means creating a new instance and filling it with the transmitted values. Now, of what exactly shall an instance be created in case of an interface type?
