SignalR is an integrated client-and-server library that enables browser-based clients and ASP.NET based server components to have a bidirectional and multistep conversation. In other words, the conversation isn't limited to a single, stateless request/response data exchange; rather, it continues until explicitly closed. The conversation takes place over a persistent connection and lets the client send multiple messages to the server and the server replies and much more interestingly sends asynchronous messages to the client.
Steps to achieve SignalR in your projects.
Step 1: Create ASP.Net Blank Application.
Step 2: Open Package Management Console
Step 3: Now we will go to the nugget.org site and search for SignalR.Sample.
Step 4. Now we will copy the installation package command and try to execute our Visual Studio Environment.
Step 5: Now we will see that the SignalR sample has been installed as your Blank ASP.Net Application.
Step 6: Now will run the application.
Step 7: Now will click on the Open Market button.
