@julian said: I'm unfamiliar with C#, and we don't handle socket establishing on our end, we just let the socket.io library handle it. Perhaps you can get a better idea by investigating the source code of this project? http://socketio4net.codeplex.com/ Hi Julian, I am using that only. Can you provide some help on how can I connect using Chrome Web socket plugin, I mean what URL to use? That might clarify my query. My objective of using C# is that I want to see whether I can get notifications from outside without logging into my local NodeBB application. Thanks!
