Why Wrapping Entity Framework Core in a Repository Pattern Is Unnecessary

A widely shared analysis argues that adding a repository pattern on top of Entity Framework Core is redundant, since EF Core's DbContext and DbSet already serve as a built-in unit of work and repository. The pattern persists largely because it was historically taught alongside EF Core, leading developers to assume the two must go together. In practice, generic repository wrappers simply pass calls through to EF Core methods, adding interface and class boilerplate without meaningful abstraction. The argument for swapping databases is also challenged, as EF Core already handles provider changes, and custom repository interfaces would need rewriting regardless. For testing — the one legitimate use case — the article suggests EF Core's in-memory and SQLite providers offer a more reliable alternative than mocking a repository layer.
