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.

Benchmarking minimal APIs with BenchmarkDotNet

BenchmarkDotNet is a framework that allows you to measure written code and compare performance between libraries written in different versions or compiled with different .NET frameworks.

This tool is used for calculating the time taken for the execution of a task, the memory used, and many other parameters.

Our case is a very simple scenario. We want to compare the response times of two applications written to the same version of the .NET Framework.

How do we perform this comparison? We take an HttpClient object and start calling the methods that we have also defined for the load testing case.

We will therefore obtain a comparison between two methods that exploit the same HttpClient object and recall methods with the same functionality, but one is written with the ASP.NET Web API and the traditional controllers, while the other is written using minimal APIs.

BenchmarkDotNet helps you to transform methods into benchmarks...
