별다른 데이터가 없으면 개발 단계에서 DB를 날리는건 큰 문제가 아닙니다.
만약에 그냥 update을 누락한거라면 update-database부터 해보세요.
혹시라도 다른 프로젝트 코드에서 DB를 건드리면서,
마이그레이션 버전이 현재 프로젝트와 상이하다거나 하면
버전이 꼬이면서 문제가 발생할 수 있습니다.
그럴땐 그냥 깔끔히 다 밀고 다시 리셋시키는게 좋습니다.

DB 상태와 EF Core에서 관리하는 상태가 꼬여서 발생하는 문제입니다.
DB를 테이블들을 다 (EFMigration 포함)날린 다음,
다시 update-database로 DB를 초기화 한 다음 테스트 바랍니다.
