    Metadata contains a reference that cannot be resolved: 'http://localhost:1177/Service1.svc'.
    The server did not provide a meaningful reply; this might be caused by a contract mismatch, a premature session shutdown or an internal server error.
    If the service is defined in the current solution, try building the solution and adding the service reference again.
