description	Create and manage Entity Framework Core database migrations including schema changes, seed data, and rollback strategies. Use when adding or modifying EF Core entities, setting up a new DbContext, applying data seeding, running dotnet ef commands, or troubleshooting migration conflicts.

Create EF Migration

Create, review, and apply Entity Framework Core migrations safely.

Workflow

Make entity/model changes in code
Generate migration with a descriptive name
Review the generated migration — verify no unintended column drops or data loss
Apply to local database and verify
Commit migration files with the related entity changes

Creating Migrations

# Generate a new migration (from the project directory containing the DbContext)
dotnet ef migrations add AddInvoiceLineItems --project src/MyApp.Data --startup-project src/MyApp.Api

# Apply to local database
dotnet ef database update --project src/MyApp.Data --startup-project src/MyApp.Api

# Rollback to a previous migration
dotnet ef database update PreviousMigrationName --project src/MyApp.Data --startup-project src/MyApp.Api

# Remove the last unapplied migration
dotnet ef migrations remove --project src/MyApp.Data --startup-project src/MyApp.Api

Best Practices

Descriptive names: AddInvoiceLineItems, RenameUserEmailToContactEmail — never Update1
Small and focused: One schema change per migration for easier rollback
Seed data: Use HasData() in OnModelCreating or IEntityTypeConfiguration<T>, not raw SQL in migrations
Review before applying: Check the generated Up() and Down() methods for unintended drops or data loss
Test locally: Always apply against a local database before committing

Checklist

Migration has a descriptive, intention-revealing name
Generated Up() and Down() methods reviewed for correctness
No unintended column drops or data loss
Migration applied successfully to local database
Seed data uses HasData(), not raw SQL
Migration files committed alongside entity changes
