Clean Architecture — Core Principles

Clean Architecture organizes code so that business rules are independent of frameworks, UI, and infrastructure.

Key rules:

1. Dependency rule — source code dependencies point inward, toward the domain.

2. Use cases — application layer orchestrates domain behavior.

3. Interfaces at boundaries — infrastructure implements interfaces defined in inner layers.

Typical layers:

Domain → Application → Infrastructure → Presentation (API/UI)

Architecture impact: Clean Architecture makes your .NET Core app testable, maintainable, and resilient to framework changes.
