Minimal APIs offer a fast, lightweight way to build services in .NET. Many developers however still use the old approach based on controllers, even for microservices. With this approach you do miss out on ahead-of-time (AOT) compilation and significantly less boilerplate code. Of course, getting started with a new approach is always difficult. In this talk, we will build a small production-ready API together with EF Core integration for data persistence, authentication and authorization using Entra ID, and a clean architecture for maintainability.

Key Topics Covered:
• Creating Minimal APIs in .NET
• Integrating EF Core
• Integrating Entra ID
• Applying clean architecture
• Unit and integration testing
• OpenAI

Prerequisites: Basic C# knowledge

Format: Live coding

Takeaways:
• Build Minimal APIs quickly and cleanly
• Write maintainable and testable API code
