- Metadata contains a reference that cannot be resolved: 'http://localhost:50926/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.
