Description Brandon White 2017-04-13 20:57:03 UTC
Attempting to execute a very simple HttpListener server results in all WebSocket requests erroring out as a 400 Bad Request.  Mono source code indicates missing functionality https://github.com/mono/mono/blob/master/mcs/class/System/System.Net/HttpListenerContext.cs#L141 in HttpListenerContext.cs

Please implement WebSocket support in HttpListener.
