Building a web API is easy. Building one that lasts, scales cleanly, tests well, and survives real-world change is where the true challenge begins.

In this fast-paced, practical session, you’ll learn how to architect modern, maintainable, and testable web APIs using ASP.NET 10. We’ll go beyond simple controller logic and explore how to design APIs that cleanly separate concerns, embrace domain-driven thinking, and keep data access decoupled from request handling.

You’ll walk away with actionable patterns for layering your APIs, organizing your code for collaboration, and preparing your services for scaling, refactoring, and testing. Whether you're building greenfield systems or untangling legacy endpoints, this talk will help you elevate your ASP.NET 10 API game.

Who Should Attend:
• ASP.NET Core developers designing or maintaining RESTful APIs
• Engineers and tech leads interested in clean architecture principles
• Backend developers frustrated with tangled controller logic and code reuse issues
• Architects seeking a lightweight yet structured approach to API development

Key Takeaways:
• Design APIs using layered architecture: Controllers, Application Layer, Domain Layer, Data Layer
• Use Dependency Injection and Abstraction to isolate and swap implementations
• Apply DTOs and ViewModels to enforce API boundaries and shape responses
• Implement unit and integration testing strategies for real-world API coverage
• Explore clean API routing, validation, and behavior reuse with filters and middleware
• Understand how to organize folders, projects, and services for scalable growth
