Проблема миграции:в базе данных уже есть объект с именем" tablename". " в ядре ASP

---

Helllo Team ,

I am Creating Application Using Asp core with Code-first Approach.

I have Created 2 models like -User, Department then I did migration and that was successfully migrated at very first time, but after that when I create a new model like :-Category and want to migrate then I am getting the error below issue.

"There is already an object named 'TableName' in the database."


It's coming if I do migration again and again when I add New model 

Что я уже пробовал:

Я пытался, но безуспешно.
