For Package Manager Console run this command:

.AspCoreProject -Data -Migrations 20190721162938_001.cs MainDbContextModelSnapshot.csUpdate:
For removing last migration use:
PM> Remove-MigrationNote: If the migration is already applied to the database, then you will get this error:
The migration '20190721162938_001' has already been applied to the database. Revert it and try again. If the migration has been applied to other databases, consider reverting its changes using a new migration.
Then run:
PM> Remove-Migration -ForceIf your migration is not the last migration. first, rollback to the migration you need by Update-Database then delete all migration classes after that migration.
PM> Update-Database -Migration 001This will revert all migrations after 001
In EF Core 5.0, you are free to move Migration files and changes their namespace manually. New migrations are created as siblings of the last migration. Alternatively, you can specify the directory at generation time as follows:
.Net core CLI
dotnet ef migrations add InitialCreate --output-dir Your/DirectoryPowerShell
Add-Migration InitialCreate -OutputDir Your\Directory
