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.

In the old days of web applications, things were simple—if you wanted a page, you had to have a physical one. However, things have since evolved and ASP.NET Core is now an MVC framework. What does that mean? Well, in MVC, there are no such thing as physical pages (although this is not exactly true);instead, it uses routing to directrequeststo routehandlers. The most common routehandlers in MVC arecontroller actions. After this chapter, you will learn how to use routing to access your controller actions.

A request is just some relative URL, such as this:


This results in more readable URLs, and is also advantageous for search engines such as Google. The subject of optimizing a site—including its public URLs—for search engines is called Search Engine Optimization (SEO).

When ASP.NET Core receives a request, one of the following two things can happen:
