During compilation? Sounds like you added the same class more than once, and that would confuse the compiler. Try renaming your class; if it works after that, you've got a copy of the class "somewhere" in your code.

When you mention "WSBackDataFrameofClass_1" in code, how would the compiler know which of those two classes you meant? Put them in a separate namespace to make them unique, or change on of the names.

The reference file created by WBServices export this definition of those classes but in a prevoius prj that are not wcf(and it work!!!!).
