Error: Table 'Table_name' already exists after Update-Database command

Following the model-first approach, I edited my Student-model (added a [Key] annotation). I then removed the migration and added a new migration using 'Add-Migration Initial' which worked fine. After that I tried and entered the command 'Update-Database' which caused the error 'Table 'Table_name' already exists'

    Table 'Student' already exists

By removing your previous migration that creates the table 'Student' EntityFramework now is generating the migration with a Create Table Script, if you want to remove a migration you must revert it from your database aswell. Now you can either recreate your database or revert/delete the 'Students' table on your database.
