In this chapter, we were introduced to server-side Blazor, which, in all aspects, deserves a book on its own, and you are encouraged to find extra reading material on Blazor should you want to be proficient in using this new addition to ASP.NET Core. We looked at how to create a basic application with server-side Blazor, and we looked at the most important components for every Blazor application.

We then introduced SignalR as one of the underlying technologies that make server-side Blazor work, and again, additional reading is recommended for more advanced readers. For most developers, just having an awareness of how SignalR fits within the Blazor ecosystem will be fine for now.

We had a look at telemetry and logging to help us with troubleshooting problems when we publish our applications in production. We learned in detail how to configure and use file logging.

Lastly, we introduced you to the fact that you can change settings, and even configure what services you want to run, depending on the environment.

Having had a walkthrough and a high-level view of most important building blocks for ASP.NET Core 3, all the way from the first chapter, we are now well placed to go into somewhat more detail, starting with ASP.NET Core MVC in the next chapter.
