Answer 1

Simply you can target a Migration by value

 Update-Database -Migration:0

Then go ahead and remove it

 Remove-Migration

Answer 2

In Package Manager Console:

Update-Database Your_Migration_You_Want_To_Revert_To

More options and explanation on how to revert migrations can be seen here

Answer 3

You can still use the Update-Database command.

Update-Database -Migration <migration name> -Context <context name>

However, judging by the name of your migration i'm assuming it's the first migration so that command may not work. You should be able to delete the entry from the __MigrationHistory table in your database and then run the Remove-Migration command again. You could also delete the migration file and just start again.

Answer 4

1.find table "dbo._EFMigrationsHistory", then delete the migration record that you want to remove. 2. run "remove-migration" in PM(Package Manager Console). Works for me.
