Are there any decent Websocket C# implementations?

I have already created my server in `System.Net.WebSockets` and now after transferring it between machines I had noticed Windows Server 2008 is not supported, are there any other implemetations which support an X509Certificate as authentication and would require minimal conversation. I have been googling for this in the past 2 hours but haven't found anything meaningful, just a collection of poorly written, poorly documented libraries that throw exceptions on the regular, specifically SuperSocket, the server implementation of which seems to be complete buggy bull. Could anyone post some sample client code from a decent library? I am growing desperate.
