Mastering Minimal APIs in ASP.NET Core

By: Andrea Tosato, Marco Minerva, Emanuele Bartolesi

Overview of this book

The Minimal APIs feature, introduced in .NET 6, is the answer to code complexity and rising dependencies in creating even the simplest of APIs. Minimal APIs facilitate API development using compact code syntax and help you develop web APIs quickly. This practical guide explores Minimal APIs end-to-end and helps you take advantage of its features and benefits for your ASP.NET Core projects. The chapters in this book will help you speed up your development process by writing less code and maintaining fewer files using Minimal APIs. You’ll also learn how to enable Swagger for API documentation along with CORS and handle application errors. The book even promotes ideas to structure your code in a better way using the dependency injection library in .NET. Finally, you'll learn about performance and benchmarking improvements for your apps. By the end of this book, you’ll be able to fully leverage new features in .NET 6 for API development and explore how Minimal APIs are an evolution over classical web API development in ASP.NET Core.

Using Entity Framework

We can absolutely say that if we are building an API, it is very likely that we will interact with data.

In addition, this data most probably needs to be persisted after the application restarts or after other events, such as a new deployment of the application. There are many options for persisting data in .NET applications, but EF is the most user-friendly and common solution for a lot of scenarios.

Entity Framework Core (EF Core) is an extensible, open source, and cross-platform data access library for .NET applications. It enables developers to work with the database by using .NET objects directly and removes, in most cases, the need to know how to write the data access code directly in the database.

On top of this, EF Core supports a lot of databases, including SQLite, MySQL, Oracle, Microsoft SQL Server, and PostgreSQL.

In addition, it supports an in-memory database that helps to write tests for our applications or to make the development cycle...
