ASP.NET Core 6 and Angular - Fifth Edition

By: Valerio De Sanctis

Overview of this book

Every full-stack ninja needs the tools to operate on front-end and back-end application development. This web app development book takes a hands-on, project-based approach to provide you with all the tools and techniques that web developers need to create, debug, and deploy efficient web applications using ASP.NET Core and Angular. The fifth edition has been updated to cover advanced topics such as Minimal APIs, Web APIs with GraphQL, real-time updates with SignalR, and new features in .NET 6 and Angular 13. You begin by building 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 (.NET 6) and Jasmine, as well as Karma for Angular. After adding authentication and authorization to your apps, you will explore progressive web applications, learning about their technical requirements, testing processes, and how to convert a standard web application to a PWA. By the end of this web development book, you will understand how to tie together the front-end and back-end to build and deploy secure and robust web applications.

It’s now time to create a new migration, and reflect the code changes to the database, by taking advantage of the code-first approach we adopted in Chapter 5, Data Model with Entity Framework Core.

Here’s a list of what we’re going to do in this section:

  • Add the identity migration using the dotnet-ef command, just like we did in Chapter 5, Data Model with Entity Framework Core
  • Apply the migration to the database, updating it without altering the existing data or performing a drop and recreate
  • Seed the data using the CreateDefaultUsers() method of SeedController that we implemented earlier on

Let’s get to work.

Adding identity migration

The first thing we need to do is to add a new migration to our data model to reflect the changes that we have implemented by extending the ApplicationDbContext class.

To do that, open a command line or PowerShell prompt, go to our WorldCitiesAPI project...
