I wonder If I could implement Observable design pattern in ASP.Net MVC 3.
I want that every time an information like a value existing on the server, the browser should be notified when there is a change.
Can I do this? If yes, how? Please post examples or link to such examples.
There’s a few things you should take a look at before you start building your own.
First, SignalR

Second, read this article that was just recently posted about the Trello web stack. They talk about how they implemented client side updating.
