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.

Understanding the OWIN pipeline

Previous versions of ASP.NET had a very close relationship with Internet Information Services (IIS), Microsoft's flagship web server that ships with Windows. In fact, IIS was the only supported way to host ASP.NET.

Wanting to change this, Microsoft defined the Open Web Interface for .NET (OWIN) specification, which you can read about at In a nutshell, it is the standard for decoupling server and application code, and for the execution pipeline for web requests. Because it is just a standard and knows nothing about the web server (if any), it can be used to extract its features.

.NET Core borrowed heavily from the OWIN specification. There are no more Global.asax, web.config, or machine.config configuration files, modules, or handlers. What we have is the following:

  • The bootstrap code in Program.Main declares a class that contains a convention-defined method (Startup will be used if no class...
