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.

The usage of HTTPS is becoming more and more common these days—not only is the performance penalty that existed in the early days now gone, but it is also significantly cheaper to get a certificate; in some cases, it may even be free—for example, Let's Encrypt ( offers such certificates. Plus, search engines such as Google boost results for sites served through HTTPS. Of course, ASP.NET Core fully supports HTTPS. We will now see how to add certificates so that we can serve our sites using HTTPS, and how to restrict access to HTTPS only.

Let's begin with certificates.


In order to use HTTPS, we need a valid certificate—one that browsers accept as valid. We can either acquire one from a root certificate provider or we can generate one, for development purposes. This won't be recognized as coming from a trusted source.

In order to generate a certificate and install...
