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.

Using areas for organizing code

An area is a feature that physically separates your app's content in a logical way. For example, you can have an area for administration and another area for the other stuff. This is particularly useful in big projects. Each area has its own controllers and views, which were discussed in Chapter 3, Routing.

In order to use areas, we need to create an Areas folder in our app at the same level as Controllers and Views. Underneath it, we will create a specific area folder—for example, Admin—and inside that, we need a structure similar to the one we have in the root—that is, with the Controllers and Views folders:

The use of areas in code

Controllers are created in the same way, but we need to add an [Area] attribute:

public class ManageController : Controller
It is OK to have multiple controllers with the same name, provided they...
