Hi I'm trying to use Fiddler2 to inspect SOAP messages exchanged between WCF client and WCF service ( both client and service are running on same machine). But problem is, whenever I use Fiddler2, WCF client reports "EndpointnotFoundException:There was no endpoint listening at http://a-PC:8100 that could accept the message à System.Net.WebException: Unable to connect to the remote server - à System.Net.Sockets-SocketException:An attempt was made to access a socket in a way forbidden by its access permissions 127.0.0.1:8888" Thank you
