First let me be honest - I haven't wrote any code for this - I am only looking for an advice... I am C# developer.
I am planning to develop an application (Web) and want automatic update like Facebook (FB), on FB when a friend post/comment, the page does not flicks, the time and posting of comments automatically. I looking for something like that - I am not doing a chat application. Explaining all will take time - It's a personal project.
A reference to reading material will be helpful, thanks.
