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.

Creating a more complex endpoint

In this section, we will create a more complex endpoint, step by step. Let's do this by writing a really simple health check endpoint, similar to what you might need if you were to run your application inside a Kubernetes cluster, or just to tell others about your health status:

  1. Microsoft advices starting with the definition of the API to add the endpoint from the developer's point of view. We do the same here. This means that we will add a MapSomething method first, without an actual implementation. This will be an extension method on the IEndpointRouteBuilder object. We are going to call it MapMyHealthChecks:
    // the new endpoint
    app.MapMyHealthChecks("/myhealth");
      
    app.MapControllerRoute(
        name: "default",
        pattern: 
            "{controller=Home}/{action=Index}/{id?}");

The new endpoint should be added...
