𝗠𝗮𝘀𝘁𝗲𝗿𝗶𝗻𝗴 𝗖𝗹𝗲𝗮𝗻 𝗔𝗿𝗰𝗵𝗶𝘁𝗲𝗰𝘁𝘂𝗿𝗲 𝗶𝗻 .𝗡𝗘𝗧: 𝗔 𝗟𝗮𝘆𝗲𝗿𝗲𝗱 𝗔𝗽𝗽𝗿𝗼𝗮𝗰𝗵

𝗪𝗵𝘆 𝗖𝗹𝗲𝗮𝗻 𝗔𝗿𝗰𝗵𝗶𝘁𝗲𝗰𝘁𝘂𝗿𝗲?
Clean Architecture keeps your .NET applications maintainable, scalable, and testable by enforcing separation of concerns. Here’s a simple breakdown of the layers and their responsibilities:

𝗣𝗿𝗲𝘀𝗲𝗻𝘁𝗮𝘁𝗶𝗼𝗻 𝗟𝗮𝘆𝗲𝗿 (𝗪𝗲𝗯/𝗔𝗣𝗜)
𝗥𝗲𝘀𝗽𝗼𝗻𝘀𝗶𝗯𝗶𝗹𝗶𝘁𝗶𝗲𝘀:
• Handles HTTP requests/responses (REST, GraphQL, gRPC)
• Uses ASP.NET Core Controllers to route requests
• Maps DTOs (Data Transfer Objects) to Application Layer commands/queries
• No business logic—delegates work to the Application Layer

𝗔𝗽𝗽𝗹𝗶𝗰𝗮𝘁𝗶𝗼𝗻 𝗟𝗮𝘆𝗲𝗿 (𝗨𝘀𝗲 𝗖𝗮𝘀𝗲𝘀)
𝗥𝗲𝘀𝗽𝗼𝗻𝘀𝗶𝗯𝗶𝗹𝗶𝘁𝗶𝗲𝘀:
• Orchestrates business workflows (e.g., Create User, Process Order)
• Defines Commands, Queries, and DTOs
• Depends only on Domain interfaces, no direct infrastructure dependencies
𝗞𝗲𝘆 𝗖𝗼𝗻𝗰𝗲𝗽𝘁𝘀:
- CQRS (Command Query Responsibility Segregation)
- Mediator Pattern (MediatR) for decoupling
- Validation & Authorization (FluentValidation, Policy-based checks)

𝗗𝗼𝗺𝗮𝗶𝗻 𝗟𝗮𝘆𝗲𝗿 (𝗖𝗼𝗿𝗲 𝗕𝘂𝘀𝗶𝗻𝗲𝘀𝘀 𝗟𝗼𝗴𝗶𝗰)
𝗥𝗲𝘀𝗽𝗼𝗻𝘀𝗶𝗯𝗶𝗹𝗶𝘁𝗶𝗲𝘀:
• Contains Entities (e.g., User, Order, Product)
• Defines Interfaces (e.g., IUserRepository, IEmailService)
• Pure business rules—no dependencies on frameworks or databases
𝗚𝗼𝗹𝗱𝗲𝗻 𝗥𝘂𝗹𝗲:
• Domain must never reference Infrastructure or UI!

𝗜𝗻𝗳𝗿𝗮𝘀𝘁𝗿𝘂𝗰𝘁𝘂𝗿𝗲 𝗟𝗮𝘆𝗲𝗿 (𝗣𝗲𝗿𝘀𝗶𝘀𝘁𝗲𝗻𝗰𝗲 & 𝗘𝘅𝘁𝗲𝗿𝗻𝗮𝗹 𝗦𝗲𝗿𝘃𝗶𝗰𝗲𝘀)
𝗥𝗲𝘀𝗽𝗼𝗻𝘀𝗶𝗯𝗶𝗹𝗶𝘁𝗶𝗲𝘀:
Implements Domain interfaces (e.g., UserRepository, SmtpEmailService)
Handles database access (EF Core, Dapper)
Integrates with external services (Auth, Logging, Cloud Storage)
𝗞𝗲𝘆 𝗣𝗿𝗶𝗻𝗰𝗶𝗽𝗹𝗲:
Dependency Injection ensures loose coupling

𝗗𝗲𝗽𝗲𝗻𝗱𝗲𝗻𝗰𝘆 𝗙𝗹𝗼𝘄
• Presentation → Application → Domain
• Infrastructure → Domain
• Domain must never depend on other layers!

𝗕𝗲𝗻𝗲𝗳𝗶𝘁𝘀
- 𝗧𝗲𝘀𝘁𝗮𝗯𝗶𝗹𝗶𝘁𝘆 - mock dependencies easily
- 𝗙𝗹𝗲𝘅𝗶𝗯𝗶𝗹𝗶𝘁𝘆 - swap databases/APIs without breaking core logic
- 𝗟𝗼𝗻𝗴-𝘁𝗲𝗿𝗺 𝗺𝗮𝗶𝗻𝘁𝗮𝗶𝗻𝗮𝗯𝗶𝗹𝗶𝘁𝘆 - clear boundaries = fewer bugs
