So far in the book you’ve learned how to use minimal APIs, Razor Pages, and Model-View-Controller (MVC) controllers to build both server-rendered applications and APIs. You know how to dynamically generate JavaScript Object Notation (JSON) and HTML code based on incoming requests, and how to use configuration and dependency injection to customize your app’s behavior at runtime. In part 4 you’ll learn how to add users and profiles to your app and how to publish and secure your apps.
In chapters 23 through 25 you’ll learn how to protect your applications with authentication and authorization. In chapter 23 you’ll see how you can add ASP.NET Core Identity to your apps so that users can log in and enjoy a customized experience. You’ll learn how to protect your Razor Pages apps using authorization in chapter 24 so that only some users can access certain pages in your app. In chapter 25 you’ll learn how to apply the same protections to your minimal API and web API applications.
Adding logging to your application is one of those activities that’s often left until after you discover a problem in production. Adding sensible logging from the get-go will help you quickly diagnose and fix errors as they arise. Chapter 26 introduces the logging framework built into ASP.NET Core. You’ll see how you can use it to write log messages to a wide variety of locations, whether it’s the console, a file, or a third-party remote-logging service.
