Preface

The simplification of code is every developer’s dream. Minimal APIs are a new feature in .NET 6 that aims to simplify code. They are used for building APIs with minimal dependencies in ASP.NET Core. Minimal APIs simplify API development through the use of more compact code syntax.

Developers using minimal APIs will be able to take advantage of this syntax on some occasions to work more quickly with less code and fewer files to maintain. Here, you will be introduced to the main new features of .NET 6 and understand the basic themes of minimal APIs, which weren’t available in .NET 5 and previous versions. You’ll see how to enable Swagger for API documentation, along with CORS, and how to handle application errors. You will learn to structure your code better with Microsoft’s new .NET framework called Dependency Injection. Finally, you will see the performance and benchmarking improvements in .NET 6 that are introduced with minimal APIs.

By the end of this book, you will be able to leverage minimal APIs and understand in what way they are related to the classic development of web APIs.
