Newly written SignalR with .Net Core 2.0 and TypeScript

Whenever we want to implement real-time web functionality in .Net then first thing comes to our mind is SignalR. What is SignalR? ASP.NET SignalR is a 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.
