Overview of this book

This latest edition of the bestselling Packt series will give you a solid foundation to start building projects using modern C# and .NET with confidence. You'll learn about object-oriented programming; writing, testing, and debugging functions; and implementing interfaces. You'll take on .NET APIs for managing and querying data, working with the fi lesystem, and serialization. As you progress, you'll explore examples of cross-platform projects you can build and deploy, such as websites and services using ASP.NET Core. This latest edition integrates .NET 8 enhancements into its examples: type aliasing and primary constructors for concise and expressive code. You'll handle errors robustly through the new built-in guard clauses and explore a simplified implementation of caching in ASP.NET Core 8. If that's not enough, you'll also see how native ahead-of-time (AOT) compiler publish lets web services reduce memory use and run faster.

Entity Framework Core is a natural way to get real data onto a website. In Chapter 12, Introducing Web Development Using ASP.NET Core, you created two pairs of class libraries: one for the entity models and one for the Northwind database context, for SQL Server and SQLite. You will now use them in your website project.

Configuring Entity Framework Core as a service

Functionality, such as Entity Framework Core database contexts, that is needed by an ASP.NET Core project should be registered as a dependency service during website startup. The code in the GitHub repository solution and below uses SQLite, but you can easily use SQL Server if you prefer.

Let’s see how:

  1. In the Northwind.Web project, add a project reference to the Northwind.DataContext project for either SQLite or SQL Server, as shown in the following markup:
    <!-- Change Sqlite to SqlServer if you prefer. -->
    <ItemGroup>
