Entity Framework 6 is a mature object-relational mapper (ORM) for .NET that lets developers work with relational databases using strongly-typed .NET objects, LINQ queries, and Code First or visual designer modeling. It is still supported by Microsoft for security fixes but is no longer actively developed, with new feature work focused on EF Core.
Use cases
- map .NET classes to relational database tables
- query databases with LINQ instead of SQL
- generate database schemas from C# entity models with Code First
- maintain legacy .NET Framework applications using EF6
- perform change tracking and unit-of-work data access
- reverse-engineer entity models from an existing database
When to choose
- you have an existing EF6 or .NET Framework codebase that already uses it
- you need EDMX/visual designer support or other EF6-only features
- you want a battle-tested, stable ORM with long-term Microsoft support for security fixes
When to avoid
- you are starting a new project on modern .NET - use EF Core instead
- you need new features, community contributions, or active bug fixes
- you need a lightweight, extensible ORM with ongoing development
