Implementing Clean Architecture in .NET 8 – A Practical Guide

By Peter French

Clean Architecture helps build maintainable, testable, and scalable .NET applications. Follow these steps to implement it effectively:

  1. Define Core Entities & Business Logic: These should have no external dependencies.
  2. Create Application Layer: Contain use-cases and business logic, referencing core entities.
  3. Implement Infrastructure Layer: Database, logging, external services, etc., linked via interfaces.
  4. Design Presentation Layer: Your Web API or MVC, depending only on the Application Layer.
  5. Dependency Injection (DI): Wire layers together using DI containers.

Benefits:

  • Easy to test.
  • Independent of frameworks and databases.
  • Improved readability and maintainability.

By following these guidelines, you’ll build cleaner, more sustainable .NET applications.
