IntroductionSignalR is a library for ASP.NET developers to simplify the process of adding real-time web functionality to applications. Real-time web functionality is the ability to have server code push content to connected clients instantly as it becomes available, rather than having the server wait for a client to request new data. Chat is often used as a SignalR example, we can do a whole lot more. Any time a user refreshes a web page to see new data, or the page implements long polling to retrieve new data, it is a candidate for using SignalR. Examples include dashboards and monitoring applications, collaborative applications (such as simultaneous editing of documents), job progress updates, and real-time forms. Stock market applications are also an example of SignalR. SignalR includes API for connection management (for instance, connect and disconnect events), and grouping connections. SignalR also provides a simple API for creating server-to-client remote procedure calls (RPC) that call JavaScript functions in the client browsers (and other client platforms) from server-side .NET code.
