javascript - How can I create a chat communication channel between 2 users in asp.net -

I want to add a chat application to my website. I've developed almost the rough part of the chat app. But I'm having trouble creating chat communication channels. I am using the web-service to insert and retrieve messages from the data base. When I add a new message, another user can not read that message until it reloads its chat window.

I'm not sure what your question is - though:

if If you want to create a chat app then why not see SignalR on the Net?

They have a demo that shows how to write chat applications (code in small amounts).

There is also a live chat app using Signal R -
