Recently on one of my machines, my client (WCF client) is having problem talking to WCF server. Both server and client are running on the same machine. The machine is Windows7 64 bit machine. It used to work fine until recently. The same software is working
fine on all other machines with exactly same configuration. I am really confused here. Could someone please let me know what could be the problem?
System.ServiceModel.Security.MessageSecurityException, System.ServiceModel, Version=18.104.22.168, Culture=neutral, PublicKeyToken=b77a5c561934e089
Security processor was unable to find a security header in the message. This might be because the message is an unsecured fault or because there is a binding mismatch between the communicating parties. This can occur if the service is configured for security
and the client is not using security.
