Hi,
We are probably going to add web sockets support to UWS at some point, but our web sockets supports won't be 100% compatible with existing, IIS8-spesicifc, .NET APIs, which Microsoft 
made unavailable to other web server implementations. This means that even if we implement web sockets, your application code will look like if(runningUnderUWS) { useUwsSockets(); } else { useIis8Sockets(); } We suspect not too many people want to do this. Everyone, please let us know if you'd have UWS-specific web socket API vs not having any.
Please 
tell Microsoft to open up web socket support in ASP.NET by 
upvoting our complaint.
Best regards,
UltiDev Team.
