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.

Exploring endpoint routing

To learn about endpoint routing, you need to learn what an endpoint is and what routing is.

Endpoints are part of an app that get executed when a route maps the incoming request to it. Let's analyze this definition in a little more detail.

A client usually requests a resource from a server. In most cases, the client is a browser. The resource is defined by a URL, which points to a specific target. In most cases, the target is a web page. It could also be a mobile app that requests specific data from a JSON web API. What data the app requests is defined in the URL.

This means that the incoming request is also defined by the URL. The executing endpoint, on the other hand, is mapped to a specific route. A route is a URL or a pattern for a URL. ASP.NET Core developers are already familiar with such a route pattern:

app.UseRouting();
app.UseAuthorization();
app.UseEndpoints(endpoints =>
{
    endpoints.MapControllerRoute...
