Entity Framework Core

Entity Framework Core (EF Core) describes itself as "a lightweight, extensible, open source and cross-platform version of the popular Entity Framework data access technology."

EF Core assumes a one-to-one mapping between entity classes and tables. All access is performed via a DbContext class, which internally manages connections and tracks changes to entities.

Supported Databases

Database specific providers are required.

EF Core 3.x supports:

  • Azure Cosmos DB
  • MariaDB
  • MySQL
  • Oracle DB
  • PostgreSQL
  • SQL Server
  • SQLite

EF Core 2.x providers are not compatible with EF Core 3.x.


See Database Providers for a current list of EF Core providers.


EF Core requires creating a subclass of DbContext. This contains the configuration needed to map classes to tables.

The Scaffold-DbContext command may be used to automatically generate the DBContext and the matching entity classes.

Alternately, the entities can be created first and be used to generate the database schema.
