What you'll learn

Building a web API that's correct, secure, and maintainable requires understanding a broad set of concepts—from routing and parameter binding to validation, authentication, and documentation. In this course, Building Minimal APIs in ASP.NET Core 10, you'll gain the ability to build a production-ready minimal API from scratch. First, you'll explore the minimal API project structure, dependency injection, routing, parameter binding, and the DTO pattern. Next, you'll discover how to craft correct responses with TypedResults, validate input with built-in DataAnnotations support, and structure your codebase for scalability using handler classes and extension methods. Finally, you'll learn how to secure your API with JWT bearer authentication and authorization policies, and document it with the built-in OpenAPI support and an interactive documentation UI. When you're finished with this course, you'll have the skills and knowledge of ASP.NET Core 10 minimal APIs needed to build secure, well-structured, and fully documented web APIs.
