Answer
The Repository Pattern abstracts the data access layer.
It provides:
- Clean separation of concerns
- Mockable interfaces for testing
- Consistent CRUD interface
Quick Answer
Repository pattern abstracts data access behind an interface. IUserRepository defines operations (FindByIdAsync, GetAll, Add). Implementation uses EF Core. Controllers inject IUserRepository - decoupled from EF Core. Benefits: testability (mock the repository), swappable data source, centralized query logic. Debate: EF Core DbContext already implements repository pattern - adding another layer may be unnecessary overhead.
