SignalR on .NET 6 - the Complete Guide: The easiest way to enable real-time two-way HTTP communication on .NET 6

Are you a web developer or do you write Internet of things (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. For example, a user of a live chat  would want to know in real time that they have received a new message.  Or an IoT device may need to be sent a command in real time.

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, which is included in ASP.NET Core.

SignalR doesn't only  enable you to achieve real-time two-way communication between  applications. It also substantially simplifies the process of enabling  all of this in the code. Under the hood, it uses various two-way  communication protocols, such as WebSocket. However, it abstracts away  all the implementation complexity of these protocols. To the developer,  working with this library will mostly consists of writing simple and  easily readable statements.

In this book, we will cover  everything you would need to know about using SignalR on .NET 6, so you  will see how to integrate it with the the latest features on ASP.NET  Core 6 and C# 10. We will cover much more than you can find in the  official documentation of the library. For example, you will learn how  to connect a plain WebSocket client to it, which may help you to write a  client in a language that isn't officially supported. Likewise, we will  cover many concepts that aren't directly related to SignalR, but are  important to its production-ready implementation. These would include  single sign-on, certificate authorization, logging, metrics and scaling  out. By the end of this book, you would be able to identify the  situations where SignalR is the best tool for the job and you would be  fully capable to implement it.
