About Entity Framework

Entity Framework (EF) simplifies working with relational databases in .NET by letting you model database entities as ordinary C# classes that are managed automatically for reads, updates and migrations.

The modern version, EF Core, is a lightweight, cross‑platform and extensible ORM for .NET 6+ that supports databases such as SQL Server, PostgreSQL, SQLite, MySQL and Azure Cosmos DB. It provides strong typing via LINQ, change tracking and built‑in migrations - ideal for modern cloud and web applications.

There is also the older EF 6 branch, which is still maintained for legacy .NET Framework projects. With EF you get powerful tools like DbContext for session and query management, DbSet for manipulating entities, and a rich ecosystem of tools and community extensions that streamline development.

Entity Framework is often used together with

.NET
C#
Git
