В настоящее время я пытаюсь создать основной проект EF, но когда я вызываю db.SaveChanges (), я получаю следующую ошибку:

Я пытался поискать в Google какую-нибудь помощь , но до сих пор пустовали ... У кого-нибудь есть идеи? Я пытаюсь подключиться к sql серверу и использую DbContextOptionsBuilder (). UseSqlServer () для базового соединения.
В настоящее время я запускаю и запускаю свой старый ноутбук windows, чтобы проверить, работает ли он. потому что я нахожусь на Ма c или нет, но я думал, что в ближайшее время у меня возникнет этот вопрос.
