Получение System.Reflection.ReflectTypeloadexception При попытке выполнить миграцию базы данных в ядро ​​.NET и EF Core ⇐ C#

[Anonymous]

Все работало нормально, и я попытался запустить миграцию, но я получаю эту ошибку. Я тестировал с несколькими dbcontexts и той же проблемой. < /P>
Есть идеи? < /P>
