The HTTP request to *.svc has exceeded the allotted timeout. The time allotted to this operation may have been a portion of a longer timeout.

Change the binding settings in ServiceReferences.ClientConfig file in your web service. Add timeout attribute.

<binding name="BasicHttpBinding_Service1" maxBufferSize="2147483647"
                    maxReceivedMessageSize="2147483647" receiveTimeout="00:10:00" sendTimeout="00:10:00" openTimeout="00:10:00" closeTimeout="00:10:00">
                </binding>
