FindUnusedPort

[rioka]

I occasionally get an error when I run tests, because the port that is selected is not actually free...

When debugging, I can see the problem is likely in MessagingProvider.FindUnusedPort: from what I can see, established connections are not excluded from the list, and eventually the service tried to bind to a non-free port.

            ICollection<int> used = IPGlobalProperties.GetIPGlobalProperties()
                                                      .GetActiveTcpListeners()
                                                      .Select(l => l.Port)
                                                      .ToList();

In my case, another application is using port 49152 (ie MinimumPort in the code), and the status of the connection is ESTABLISHED, so it is erroneously not included in the list of used ports I guess.

Yeah that needs GetActiveTcpConnections adding as well as listeners
