Entity Framework

Microsoft's primary object-relational mapper (ORM) for .NET that eliminates the need for most data-access boilerplate.

Entity Framework (EF Core) functions as the standard data-access layer for modern .NET applications. It maps C# classes to database tables: allowing developers to query data using LINQ (Language Integrated Query) instead of manual SQL strings. The framework supports major providers (SQL Server, PostgreSQL, and SQLite) and automates schema management through a robust migrations system. By handling change tracking and relationship mapping out of the box, EF Core accelerates development cycles for enterprise-grade software.
