Entity Framework
Entity Framework (EF) is Microsoft's object-relational mapper (ORM) for .NET. It allows developers to work with a database using .NET objects, rather than writing raw SQL queries. EF automatically translates those objects into database commands, handling data retrieval, updates, and relationships. Versions 3+ (including EF Core) modernised the framework to be lightweight, cross-platform, and cloud-friendly. For non-technical readers, think of EF as a "translator" between business software and the database. Developers can write logic in a familiar language (C#) while EF ensures the right data is saved or retrieved from the underlying SQL database.
Official WebsiteWhen to use Entity Framework
Use Entity Framework when building .NET applications that interact with relational databases. It suits enterprise apps, APIs, and cloud services where productivity, maintainability, and data safety matter.
Why choose Entity Framework?
Teams choose EF for its developer productivity, integration with .NET, and support for LINQ (Language Integrated Query), which allows writing queries in C#. It reduces boilerplate code and improves maintainability.
