Feature slicing and clean architecture in C# solve different problems and are not mutually exclusive. Clean architecture enforces dependency direction — keeping business logic isolated from infrastructure — while feature slicing prioritizes cohesion and discoverability by grouping code by business capability. The post walks through concrete .NET project structures and code examples for each approach, provides a direct comparison table across dimensions like testability, onboarding, and infrastructure coupling, and offers a practical decision framework. Small teams building CRUD-heavy APIs benefit most from feature slicing; complex domains with rich business rules favor clean architecture. A hybrid approach — clean architecture at the project level with feature slices inside the application layer — is also detailed as a way to get both discoverability and dependency protection.
