Service operations can only operate on concrete implementations. This is not a limitation of WCF, this is a limitation (or, feature) of WSDL. So, if you want to accept any type to a generic Load() operation, and specify the type in the call, you'll have to design a contract that receives the type T as a parameter, and returns a List<object> or object[] that is an array of that type. I think you are fixated on the syntax looking like remoting, and generics...when what you really want is a solution that fits with semantics of service design.

Why not this?

List<object> Load(string objectType);
