Are you a web developer or do you write IoT software? If so, you would know that many web and IoT development projects these days require the ability to establish a persistent connection between a client and a server without having to keep sending repeated requests from the client. As you may also know, such functionality may be hard to implement.
However, if you can build your server-side application on ASP.NET Core, there is a way to make this whole process easy. There is a library called SignalR. This is what I'm going to talk about in this course. As well as doing all the heavy lifting for you, the library abstracts away all complex implementation details, so your code can be made extremely simple.
However, as you would already know, nothing in programming is simple in absolute terms. Programming is a complex activity, so even those concepts that are relatively simple require some practice and studying.
This is why I've created this course. By the end of it, you should be able to build a web application that clients will be able to establish a persistent connection with and exchange the data with in real time.
This is the second SignalR course that I have published. The previous one was about using SignalR on .NET Core 2.2. However, quite a lot has changes since then. .NET 5 has since been released and SignalR has also received several updates. So, this is an updated version of the course. The second edition.
