Modern Web Development with ASP.NET Core 3 - Second Edition

By: Ricardo Peres

Overview of this book

ASP.NET has been the preferred choice of web developers for a long time. With ASP.NET Core 3, Microsoft has made internal changes to the framework along with introducing new additions that will change the way you approach web development. This second edition has been thoroughly updated to help you make the most of the latest features in the framework, right from gRPC and conventions to Blazor, which has a new chapter dedicated to it. You’ll begin with an overview of the essential topics, exploring the Model-View-Controller (MVC) pattern, various platforms, dependencies, and frameworks. Next, you’ll learn how to set up and configure the MVC environment, before delving into advanced routing options. As you advance, you’ll get to grips with controllers and actions to process requests, and later understand how to create HTML inputs for models. Moving on, you'll discover the essential aspects of syntax and processes when working with Razor. You'll also get up to speed with client-side development and explore the testing, logging, scalability, and security aspects of ASP.NET Core. Finally, you'll learn how to deploy ASP.NET Core to several environments, such as Azure, Amazon Web Services (AWS), and Docker. By the end of the book, you’ll be well versed in development in ASP.NET Core and will have a deep understanding of how to interact with the framework and work cross-platform.

Hosting is the process that is used to run your ASP.NET Core application. In ASP.NET Core, you have two out-of-the-box hosting choices:

  • Kestrel: The cross-platform host, which is set by default
  • HTTP.sys (WebListener in ASP.NET Core pre-2.x): A Windows-only host

If you want your application to run on different platforms, not just on Windows, then Kestrel should be your choice, but if you need to target only Windows, then WebListener/HTTP.sys may offer better performance, as it utilizes native Windows system calls. You have to make this choice. By default, the Visual Studio template (or the ones used by the dotnet command) uses Kestrel, which is appropriate for most common scenarios. Let's learn about how we can choose what's best for our purposes.

Choosing the best host

You should compare the two hosts to see how well they behave in stressful situations. Kestrel is the default one and is...
