centrifuge-csharp's Issues

Client OnError called with a System.IO.IOException, when trying to connect to server

Hi !

I facing an issue, I don't know why it is happening. I'm trying to connect to a server, but the OnError callback of the client is called with an IOException.

It comes from the Client.SendConnect() method, when it calls HandleConnectReply() : Client.SendConnect()

The catch block states that it // Should never happen. so I have no idea what happening.
