How do you rollback or revert a migration?

Short answer: To remove the last migration before applying it: dotnet ef migrations remove To rollback the database to a previous migration: dotnet ef database update MigrationName To rollback all migrations: dotnet ef database update 0

Real-world example (ShopNest)

When ShopNest adds a DiscountCode column, you create a migration, review the SQL, then apply it on staging before production.
