What you'll learn

Building production-ready minimal APIs requires more than defining endpoints—it demands a solid understanding of architecture, routing, validation, versioning, and API documentation. In this course, Minimal APIs Deep Dive in ASP.NET Core 10, you'll gain the ability to architect and optimize minimal APIs for real-world, production-scale scenarios. First, you'll explore how minimal APIs work under the hood, including the RequestDelegateFactory, endpoint routing, and the middleware pipeline. Next, you'll discover composable endpoint groups with layered conventions, source-generator-based mapping with Mapperly, reusable endpoint filter chains, and centralized validation and error handling strategies. Finally, you'll learn how to customize OpenAPI generation with document and operation transformers, implement API versioning with version-specific specifications, and stream responses with IAsyncEnumerable and server-sent events. When you're finished with this course, you'll have the skills and knowledge of ASP.NET Core minimal API architecture needed to make informed decisions and build robust, well-documented APIs for production environments.
