Customizing ASP.NET Core 6.0 - Second Edition

By: Jürgen Gutsch

Overview of this book

ASP.NET Core is packed full of hidden features for building sophisticated web applications – but if you don’t know how to customize it, you’re not making the most of its capabilities. Customizing ASP.NET Core 6.0 is a book that will teach you all about tweaking the knobs at various layers and take experienced programmers’ skills to a new level. This updated second edition covers the latest features and changes in the .NET 6 LTS version, along with new insights and customization techniques for important topics such as authentication and authorization. You’ll also learn how to work with caches and change the default behavior of ASP.NET Core apps. This book will show you the essential concepts relating to tweaking the framework, such as configuration, dependency injection, routing, action filters, and more. As you progress, you'll be able to create custom solutions that meet the needs of your use case with ASP.NET Core. Later chapters will cover expert techniques and best practices for using the framework for your app development needs, from UI design to hosting. Finally, you'll focus on the new endpoint routing in ASP.NET Core to build custom endpoints and add third-party endpoints to your web apps for processing requests faster. By the end of this book, you'll be able to customize ASP.NET Core to develop better, more robust apps.

Configuring logging

In previous versions of ASP.NET Core (that is, before version 2.0), logging was configured in Startup.cs. As a reminder, since version 2.0, the Startup.cs file has been simplified, and a lot of configurations have been moved to the default WebHostBuilder, which is called in Program.cs. Also, logging was moved to the default WebHostBuilder.

In ASP.NET Core 3.1 and later versions, the Program.cs file gets more generic, and IHostBuilder will be created first. IHostBuilder is pretty useful for bootstrapping an application without all of the ASP.NET web stuff. We'll learn a lot more about IHostBuilder later on in this book. With this IHostBuilder, we create IWebHostBuilder to configure ASP.NET Core. In ASP.NET Core 3.1 and later versions, we get IWebHostBuilder with the webBuilder variable:

public class Program
{
    public static void Main(string[] args)
    {
        CreateHostBuilder...
