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.

Technical requirements

To follow the descriptions in this chapter, you will need to create an ASP.NET Core 6.0 Web API application. You can either use one of the following options:

  • Option 1: Click on the New | Project command in the File menu of Visual Studio 2022 – then, choose the ASP.NET Core Web API template. Select a name and the working directory in the wizard and be sure to uncheck the Use controllers (uncheck to use minimal APIs) option in the next step.
  • Option 2: Open your console, shell, or Bash terminal, and change to your working directory. Use the following command to create a new Web API application:
    dotnet new webapi -minimal -o Chapter02

Now, open the project in Visual Studio by double-clicking the project file, or in Visual Studio Code, by typing the following command in the already open console:

cd Chapter02

Finally, you can safely remove all the code related to the WeatherForecast sample, as we don’t need it for this chapter...
