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.

Localizing a minimal API application

To enable localization within a minimal API application, let us go through the following steps:

  1. The first step to making an application localizable is to specify the supported cultures by setting the corresponding options, as follows:
    var builder = WebApplication.CreateBuilder(args);
    var supportedCultures = new CultureInfo[] { new("en"), new("it"), new("fr") };
    builder.Services.Configure<RequestLocalizationOptions>(options =>
       options.SupportedCultures = supportedCultures;
       options.SupportedUICultures = supportedCultures;
       options.DefaultRequestCulture = new 

In our example, we want to support three cultures – English, Italian, and French – so, we create an array of CultureInfo objects.

We’re defining neutral cultures, that is, cultures that have...
