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.

Improvements with minimal APIs

Minimal APIs were designed not only to improve the performance of APIs but also for better code convenience and similarity to other languages to bring developers from other platforms closer. Performance has increased both from the point of view of the .NET framework, as each version has incredible improvements, as well as from the point of view of the simplification of the application pipeline. Let’s see in detail what has not been ported and what improves the performance of this framework.

The minimal APIs execution pipeline omits the following features, which makes the framework lighter:

  • Filters, such as IAsyncAuthorizationFilter, IAsyncActionFilter, IAsyncExceptionFilter, IAsyncResultFilter, and IasyncResourceFilter
  • Model binding
  • Binding for forms, such as IFormFile
  • Built-in validation
  • Formatters
  • Content negotiations
  • Some middleware
  • View rendering
  • JsonPatch
  • OData
  • API versioning
