Minimal APIs in ASP.NET Core

What’s included?

• Minimal APIs in ASP.NET Core – The Online Text Course

All materials are available in .NET 9 with Community Support over Discord.

What you’ll learn?

We’ll start by breaking down Minimal APIs and why they’re a game-changer in API development. Next, you’ll set up your project the right way—configuring environment-based settings, integrating Serilog for logging, and building a strong foundation for scalability.

Then, we’ll dive into structuring your application with Onion Architecture. You’ll design model classes, work with DbContext, and implement repositories, services, and the Unit of Work pattern to keep your code clean and maintainable.

But that’s just the beginning. APIs thrive on HTTP requests, and you’ll master them all. You’ll fetch data with GET, validate inputs with POST, PUT, and PATCH, and handle errors gracefully using global exception handling.

As you advance, you’ll unlock powerful techniques to elevate your APIs. You’ll implement pagination, filtering, searching, and sorting to manage large datasets efficiently. You’ll also add HATEOAS for hypermedia-driven APIs, version your endpoints to ensure future compatibility, and document everything with Swagger. Plus, you’ll secure your API with authentication, authorization, caching, and rate limiting—essential for high-performance, production-ready applications.

Every lesson goes beyond the how to explain the why. By the end, you won’t just understand Minimal APIs in ASP.NET Core — you’ll confidently design scalable, secure, and maintainable systems.

Finally, you’ll learn to write and run integration tests, ensuring your API meets the highest quality standards.
