Entity Framework Core (EF Core) is Microsoft's modern object-database mapper for .NET, supporting LINQ queries, change tracking, updates, and schema migrations. It works with SQL Server, SQLite, PostgreSQL, MySQL, Azure Cosmos DB, and other databases through a provider plugin API.
Use cases
- map C# classes to database tables with an ORM
- query a database using LINQ instead of raw SQL
- run database schema migrations for a .NET app
- build a data access layer for ASP.NET Core
- use SQLite or SQL Server from a .NET application
- track entity changes and persist updates automatically
When to choose
- you're building .NET applications that need relational or Cosmos DB data access
- you want LINQ-based querying with compile-time checked queries
- you need schema migrations and change tracking out of the box
- you want a Microsoft-supported, MIT-licensed ORM with broad database providers
When to avoid
- you need raw SQL control or extreme performance tuning (consider Dapper or ADO.NET)
- your project is not on the .NET platform
- you need a NoSQL document store other than Azure Cosmos DB without a third-party provider
