What you'll learn

Without proper documentation, even the best-designed APIs remain underutilized and create friction for developers. In this course, Generating OpenAPI Contracts in ASP.NET Core 10, you'll gain the ability to create comprehensive, accurate, and professional API documentation that enhances developer experience and accelerates API adoption. First, you'll explore how to generate OpenAPI specifications from your ASP.NET Core APIs and create interactive documentation UIs with Scalar. Next, you'll discover how to customize and improve your specifications using XML comments, data annotations, attributes, and transformers to ensure accuracy. Finally, you'll learn how to deal with versioning, authentication, and build-time generation to create production-ready API documentation. When you're finished with this course, you'll have the skills and knowledge of OpenAPI specification generation needed to document your ASP.NET Core APIs professionally and maintain that documentation as your API evolves.
