Let’s take a quick peek at SignalR and how we use it.
SignalR is an open-source library available in ASP.NET, to help developers add real-time features in web applications and more. Chat is the most common application that you can think of, there is a lot more you can do.
SignalR can be used to add any sort of “real-time” web functionality like dashboards, collaborative tools that require simultaneous editing of documents, job progress updates, and real-time forms. It can enable completely new types of web applications that need high-frequency updates from the server. One of the most common examples is real-time gaming.
