Entity Framework Core

A lightweight, extensible, and cross-platform object-relational mapper for .NET.

EF Core serves as the primary data access layer for .NET developers: it maps C# objects to relational tables across providers like SQL Server, PostgreSQL, and MySQL. By using LINQ (Language Integrated Query), it provides type-safe data retrieval without the need for manual SQL strings. The framework handles complex tasks like schema migrations, relationship mapping (one-to-many or many-to-many), and change tracking automatically. It is optimized for performance in ASP.NET Core environments and supports modern features such as compiled queries and connection pooling.
