Create APIs that embody simplicity, scalability, and precision with proven development techniques and the robust features of .NET

Key Features

• Get to grips with API design, architecture, and development methodologies to create elegant and scalable APIs in .NET
• Get insights into contemporary trends and tools shaping the API industry
• Explore both basic and advanced topics such as optimization, data integration, and caching

Book Description

Written by an esteemed technology leader, a .NET specialist, and Microsoft MVP for Developer Technologies, Minimal APIs in ASP.NET 9 provides you with specialized insights into the latest advancements in .NET technology, particularly minimal APIs.

You’ll get your first minimal API set up and running, before exploring the anatomy of a typical minimal API project, seeing how the framework can be used to create various HTTP endpoints, route, and validate requests, as well as enhancing those requests with custom middleware. After covering the basics, you’ll move on to data mapping, managing important dependencies through dependency injection and integrating your minimal APIs with data sources such as Entity Framework, Dapper, and SQL databases for creating CRUD operations. The chapters also walk you through performance optimization, asynchronous programming, and caching, which’ll allow you to examine the more advanced aspects of minimal API development, with code examples reflecting real-world scenarios.

By the end of this book, you’ll be armed with the necessary best practices and skills needed for deploying performant, elegant, and scalable minimal APIs in .NET.
