I n this post, let us build a small proof of concept for SignalR with two basic screens. Users.aspx: A sample user home page. Admin.aspx: This page is for administrator for sending notifications to all Users. What are we doing? Admin can make announcements. Can just post a title, a message and send it simultaneously to all the users who have opened up Users screen at that point of time. Not a big deal? But, we are going to do that without making the Users screen to refresh to get notifications in any way. No timer is used. Users should see the notification via a live connection .Works like a call over a telephone!
