Почему EF сообщает о двойном исключении DbUpdateException в ответ на неправильно настроенную защиту SQL?

Question

На самом деле я уже знаю, как решить проблему, которая вызвала ошибку: исправить безопасность в моей базе данных, чтобы разрешить моему приложению права на запись в нужную таблицу.

Что я не знаю, так это почему SQL проблема с разрешениями (которую вы можете увидеть в глубине внутреннего исключения: The INSERT permission was denied on the object 'AccountRelationship') привела к тому, что язык DbUpdateException ссылается на мою сущность как «дубликат», когда это действительно не так.

Это так? хорошо известное поведение EF?

Duplicate AccountRelationship

BusinessRelationshipId, BusinessRelationshipSalesforceId, GeneratorId, CustomerId
