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.

Endpoint routing

Endpoint routing was introduced in ASP.NET Core 2.2 and is now the default mechanism as of 3.0. The main advantage is that it supports many different mechanisms that, although leveraging routing and middleware, are very different—MVC, Razor Pages, gRPC, Blazor, SignalR, and whatnot. You still register the services you want in ConfigureServices and then add the middleware to the pipeline using extension methods in the Configure method. Endpoint routing makes the framework more flexible because it decouples route matching and resolution from endpoint dispatching, which used to be all part of the MVC functionality.

There are three required method calls:

  • AddRouting: Where we register the required services and optionally configure some of its options (ConfigureServices)
  • UseRouting: Where we actually add the routing middleware (Configure); this matches requests to an endpoint
  • UseEndpoints: Where we configure the...
