Reclaim Your Domain: Why DBContext Abstraction Protects Your Codebase from ORM Coupling

This article challenges the conventional wisdom that Entity Framework's DBContext and DbSet abstractions are redundant. The author argues the real question is not whether to abstract the ORM, but whether your domain layer should depend on data access implementation details. By treating DBContext as a Microsoft-controlled interface rather than a true business repository, developers become vulnerable to framework version changes. Proper repository abstraction—speaking the language of business logic rather than SQL mechanics—is essential for maintaining domain independence and avoiding vendor lock-in.
