Я работаю над несколько простым приложением InventoryTracker MVC5, в котором у меня возникают некоторые проблемы с получением моей LocalDatabase до Seed()
.MVC EntityFramework Code-First Migrations - Seed() Неудача с AmbiguousMatchException?
Когда я запускаю команду update-database
на моем коде ниже, я получаю исключение следующим образом на линии context.INV_Assets.AddRange(invAssets)
:
An exception of type 'System.Reflection.AmbiguousMatchException' occurred in mscorlib.dll but was not handled in user code. Additional information: Ambiguous match found.
Кто-нибудь есть мысли о том, что в моем INV_Assets - Seed()
вызывает проблему? Не существует InnerException, и я не могу получить больше подробностей об этом.
