EF Core supports three main approaches:

1. Code First: Define entity classes first, then generate database schema
   • Start with C# classes (entities)
   • Use migrations to create and update database
   • Good for new projects with full control over data model
2. Database First: Start with existing database, generate entity classes
   • Use Scaffold-DbContext command
   • Generates DbContext and entity classes from existing database
   • Good for existing databases or database-driven development
3. Model First: Design model using visual designer (less common in EF Core)
   • Primarily supported through external tools
   • Not as prominent as in EF6
