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.

Pages

Pages are special kinds of Blazor components that can be accessed directly by the browser (this is not quite true, but we can think of it like that). They have the .razor extension and, by convention, should be placed in a folder called Pages under the root folder of our app (or in a folder underneath it). The first line of the file should have a @page directive (similarly to Razor Pages)—something like this:

@page "/Home"

This may seem unnecessary, but this should contain the route that the page accepts, which is likely the same name of the file, without the .razor extension, but doesn't have to be so. If a page does not have a @page directive, it cannot be accessed by Blazor directly. We'll talk more about this when we discuss routing later on in the chapter.

All Blazor components (and a page is a component) must implement an IComponent interface, of which ComponentBase is the most obvious, already implemented choice....
