Erro com Migratios .Net 2 ou .Net 7 - Contexto

Com um projeto novo, mudei tudo para o .Net 7 e atualizei os pacotes. Depois add o Microsoft.EntityFrameworkCore.Design no .WebApp E as Migrations rodaram de boas...

Tive ajuda do pessoal do Discord @Bruno Aragão

Deu certo, mas o servidor está dando status 500

As duas URLs estão voltando 500.

Tentei mudar algumas coisas mas não conseguir fazer funcionar. Ele continua dando status 500.

Deletei o projeto e fiz novamente o download do projeto do professor. Mas agora eu instalei as SDKs que o proprio visual estudio recomendou e as migratios funcionaram perfeitamente.
