Clean Architecture in .NET: Moving Beyond Generic Repositories and Leveraging IServiceScopeFactory
- Architectural patterns like Clean Architecture, DDD, and CQRS are widely adopted but can lead to over-engineering with unnecessary abstractions like generic IRepository interfaces.
- Clean Architecture separates software design into core layers: Entities, Use Cases, Interface Adapters, and Infrastructure, guided by the Dependency Rule for testability and maintainability.
- Understanding when architectural patterns add value (complex business domains, shared understanding in large teams) versus when they become overhead (CRUD-centric apps, small teams) is crucial.
- The Generic Repository anti-pattern, like IRepository
, creates limitations such as semantic mismatch, abstraction leakage, and promoting anemic domain models. - Intent-Driven Repository Design offers better clarity, encapsulation, testability, and domain alignment by reflecting real business operations in interfaces.
- IServiceScopeFactory in .NET addresses the challenge of service lifetimes by enabling safe resolution of scoped services in non-request contexts like background services.
- Implementation recommendations include starting simple, focusing on intent-driven interfaces, respecting service lifetimes, iterative refinement, and aligning team capabilities with architectural choices.
- Effective software architecture should balance structure with pragmatism, tailoring implementations to actual requirements and creating maintainable, testable, comprehensible code.
- Understanding when patterns add value or introduce unnecessary complexity helps in making informed architectural decisions that serve both immediate needs and long-term maintainability.
