Customizing ASP.NET Core 5.0

Overview of this book

ASP.NET Core is the most powerful Microsoft web framework. Although it’s full of rich features, sometimes the default configurations can be a bottleneck and need to be customized to suit the nature and scale of your app. If you’re an intermediate-level .NET developer who wants to extend .NET Core to multiple use cases, it's important to customize these features so that the framework works for you effectively. Customizing ASP.NET Core 5.0 covers core features that can be customized for developing optimized apps. The customization techniques are also updated to work with the latest .NET 5 framework. You’ll learn essential concepts relating to optimizing 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 application development book, you’ll have the skills you need to be able to customize ASP.NET Core to develop robust optimized apps.

To get the most out of this book

The readers should have basic knowledge of ASP.NET Core and C#, as well as of Visual Studio, Visual Studio Code, or any other code editor that supports ASP.NET Core and C#.

You should install the latest .NET 5 SDK on your machine. Please find the latest version on https://dotnet.microsoft.com/download/dotnet-core/.

Feel free to use any code editor you like that supports ASP.NET Core and C#. We recommend using Visual Studio Code (https://code.visualstudio.com/), which is available on all platforms and is used by the author of this book.

All the projects in this book will be created using a console, Command Prompt, shell, or PowerShell. Feel free to use whatever console you are comfortable with. The author uses Windows Command Prompt, hosted in the cmder shell (https://cmder.net/). We don’t recommend using Visual Studio to create the projects, because the basic configuration might change, and the web projects will start on a different port than described in this book.

Are you stuck with .NET Core 3.1? If you are not able to use .NET 5 on your machine for whatever reason, all the samples are also available and work with .NET Core 3.1. The chapters contain comparisons to .NET Core 3.1 whenever there are differences to .NET 5, as version 3.1 is still the current Long-Term Support version of .NET Core.

If you are using the digital version of this book, we advise you to type the code yourself or access the code via the GitHub repository (link available in the next section). Doing so will help you avoid any potential errors related to the copying and pasting of code.
