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.

Understanding Razor class libraries

Razor class libraries were introduced to ASP.NET Core 2.2. What it means is that all components—code- or file-based—can be added to an assembly and then referenced by an application. If, for example, this class library contains multiple .cshtml files, we can refer to them in our controllers or provide overrides for them in the application, provided that the same path is respected. Think, for example, of the authentication and registration views provided by Identity; if you don't like any of them, you can provide an alternative one while keeping the others.

Razor class libraries can be created using Visual Studio:

It essentially produces a .csproj file that uses the Microsoft.NET.Sdk.RazorSDK (Razor class libraries) instead of Microsoft.NET.Sdk.Web(for web applications) or Microsoft.NET.Sdk (for .NET Core assemblies):
