Niezgodność ContractFilter w EndpointDispatcher?

Question

Oto jestem wywołanie metody z usługi hostingowej relaksującego w przeglądarce

https://eshop/LinkService/LinkService.svc/GetStudentObj 

i otrzymuję następujący błąd pliku

The message with Action '' cannot be processed at the receiver, due to a ContractFilter mismatch at the EndpointDispatcher. This may be because of either a contract mismatch (mismatched Actions between sender and receiver) or a binding/security mismatch between the sender and the receiver. Check that sender and receiver have the same contract and the same binding (including security requirements, e.g. Message, Transport, None)

Jakieś sugestie?
