Real-time application - an alternative to asp.net for node.js and socket.io

Question

I work with asp.net.

I want to write an application in real time without an ajax request.

I need free technology - something like node.js and socket.io.

What is the alternative for asp.net - node.JS and SOCKET.IO?

Answer 2

Why not use httplistener / tcplistener? It is in BCL and is part of the ECMA standard. So, I think you can say that it is free? Not?

Answer 3

I have used AspComet in the past.
