WCF: System.Net.SocketException - Only one usage of each socket address (protocol/network address/port) is normally permitted
问题 I have a WCF service and a Web application. Web application makes calls to this WCF service in a continous manner a.k.a polling. In our production environment, I receive this error very rarely. Since, this is an internal activity users were not aware of when this error is thrown. Could not connect to http://localhost/QAService/Service.svc. TCP error code 10048: Only one usage of each socket address (protocol/network address/port) is normally permitted 127.0.0.1:80. ---> System.Net
