.NET8 Identity EF Core MySql 마이그레이션 문제와 해결방법

ef provider는 pomelo 사용했습니다. 아직 pomelo 8버전은 아직 베타 버전이라 이런 문제가 있는 것 같습니다.

커넥션 스트링만 바꾼상태에서 dotnet ef database update 진행하면 마이그레이션이 실패합니다.

대략적인 원인은 프로바이더에서 스트링 멤버를 죄다 TEXT로 잡아줍니다.
해결방법은 마이그레이션 파일을 직접 맞게 다른 스트링타입으로 바꿔주시면 됩니다.
우선 TEXT를 다 VARCHAR(길이)로 잡아주니 문제없이 마이그레이션 되는 것을 확인했습니다.
