RaTemplate.Api.Contracts

Api.Contracts project is a valid pattern, often used in different scenarios:

  • Client SDKs: If you were building a client SDK (e.g., a .NET client library to consume your own API), you could put the request/response DTOs in a shared Contracts library. This would allow both the API and the client to share the same data models without the client needing to reference your entire Application project.
  • Microservices Communication: In a microservices environment, a shared Contracts library can contain the DTOs and events that are exchanged between different services.

🏛️ Architectural Principles​

  • Independence: This project has zero dependencies on any other project within the solution. It does not know about the Application, Infrastructure, or Api layers. This is the most critical rule of the Domain layer.
