To structure a C# backend solution using Clean Architecture, separate your code into Domain, Application, Infrastructure, Persistence, and API layers. This enforces isolation of business logic and ensures dependency rules flow inward toward the domain.

The Domain layer in Clean Architecture holds core business logic and entities. It is completely isolated from external concerns, meaning it has no dependencies on the Application, Infrastructure, Persistence, or API layers.

Apply a 5-layer Clean Architecture model when starting a new C# backend project or refactoring an existing one. This approach ensures your software remains scalable, maintainable, and testable through strict separation of concerns.

Yes, Clean Architecture works seamlessly with Domain-Driven Design in C# by aligning the isolated Domain layer with DDD concepts. This combination enforces separation of concerns between business logic, application use cases, and infrastructure implementations.

The best way to organize folder conventions for C# Clean Architecture tests is to establish a clear directory structure that mirrors your project layers. This provides a detailed blueprint for structuring scalable solutions and testing strategies.
