ASP.NET Core 5 and Angular - Fourth Edition

By: Valerio De Sanctis

Overview of this book

Learning full-stack development calls for knowledge of both front-end and back-end web development. ASP.NET Core 5 and Angular, Fourth Edition will enhance your ability to create, debug, and deploy efficient web applications using ASP.NET Core and Angular. This revised edition includes coverage of the Angular routing module, expanded discussion on the Angular CLI, and detailed instructions for deploying apps on Azure, as well as both Windows and Linux. Taking care to explain and challenge design choices made throughout the text, Valerio teaches you how to build a data model with Entity Framework Core, alongside utilizing the Entity Core Fluent API and EntityTypeConfiguration class. You’ll learn how to fetch and display data and handle user input with Angular reactive forms and front-end and back-end validators for maximum effect. Later, you will perform advanced debugging and explore the unit testing features provided by xUnit.net (.NET 5) and Jasmine, as well as Karma for Angular. After adding authentication and authorization to your apps, you will explore progressive web applications (PWAs), learning about their technical requirements, testing, and converting SWAs to PWAs. By the end of this book, you will understand how to tie together the front end and back end to build and deploy secure and robust web applications.

Back-end debugging

In this section, we'll learn how to make use of the debug features offered by the Visual Studio environment to take a look at the server-side life cycle of our web application and understand how we can properly troubleshoot some potential flaws.

However, before doing that, let's spend a couple of minutes seeing how it works for the various operating systems available.

Windows or Linux?

For the sake of simplicity, we'll take for granted that we're using the Visual Studio Community, Professional, or Enterprise edition for Windows operating systems. However, since .NET Core and .NET 5 have been designed to be cross-platform, there are at least two options for those who want to debug in other environments, such as Linux or macOS:

  • Using Visual Studio Code, a lightweight and open source alternative to Visual Studio available for Windows, Linux, and macOS with full debug support
  • Using Visual Studio, thanks to the Docker...
