Are there any SPDY/WebSockets Libraries for .NET available?

Question

I want to develop a Windows 8 Metro style app and wonder if there are any libraries for SPDY or Websockets protocols available? They should be free too :-)

Answer 1

WebSocket

A list of WebSocket clients (including .NET ones) can be found here: http://www.leggetter.co.uk/real-time-web-technologies-guide#websocket-client-libraries

.NET 4.5 has a WebSocket namespace and a number of classes: http://msdn.microsoft.com/en-us/library/hh159285.aspx

There also appears to be a Windows Store apps specific class (MessageWebSocket): http://msdn.microsoft.com/en-us/library/windows/apps/windows.networking.sockets.messagewebsocket.aspx
