In WCF Service programming, the following error occurs when the client adds a reference service: Metadata contains reference that cannot be parsed: "net. TCP: // 192.168.1.105: 1314/loginservice ". The socket connection has been suspended. This may be caused by an error in message processing, remote host receiving timeout, or potential network resource problem
