What are migrations?

How are they used in Code First?

Migrations in EF Core are a way to:

• Track schema changes over time
• Apply those changes to the database

📦 Basic commands:

• Add-Migration MigrationName
• Update-Database
• Remove-Migration
• Script-Migration

🔄 Migrations are classes containing Up() and Down() methods (for applying and reverting

changes).

📌 They are essential for schema versioning in Code First.
