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.

Storing a structured log with Serilog

As we just discussed, tracking structured objects in the log helps us tremendously in understanding errors.

We, therefore, suggest one of the many logging frameworks: Serilog.

Serilog is a comprehensive library that has many sinks already written that allow you to store log data and search it later.

Serilog is a logging library that allows you to track information on multiple data sources. In Serilog, these sources are called sinks, and they allow you to write structured data inside the log applying a serialization of the data passed to the logging system.

Let’s see how to get started using Serilog for a minimal API application. Let’s install these NuGet packages. Our goal will be to track the same information we’ve been using so far, specifically Console and ApplicationInsights:
