SignalR – Real-time web communication between Client and Server Easy c# [Part 1 of 2]

What is SignalR ?

ASP.NET SignalR is a new library for ASP.NET developers that makes developing real-time web functionality easy. SignalR allows bi-directional communication between server and client. Servers can now push content to connected clients instantly as it becomes available. SignalR supports Web Sockets, and falls back to other compatible techniques for older browsers. SignalR includes APIs for connection management (for instance, connect and disconnect events), grouping connections, and authorization.

Features of this exercise after you complete:

# Send real time message to client without client refreshing the page

# Receive real time communication or message from client without refreshing the page.

#Send message to all connected clients.

# Send message to specific client.

# Send message to all client except one who sent it…

# This is a proof of concept …. you can extend it to the way you want…
