Я пытаюсь запустить приложение MusicStore на Raspberry Pi 3, используя систему Windows IoT с .NET Core 2.0.4.
Мне удалось запустить его на Raspberry с помощью Ubuntu, но в Windows я получаюошибка из снимок экрана (извините, что не скопировал его, но я не получил ошибку в замазке, поэтому мне нужно использовать командную строку Windows IoT, и я нигде не могу скопировать этот текст).
Обе системы подключались к базе данных на моем ПК, и linux смог запустить приложение, когда Windows не работает, так что это не ошибка строки подключения.Раньше у меня была проблема с отсутствующим sni.dll, но, как предложено в этой теме Я исправил его, скопировав Unix.
Есть идеи, что не так?
РЕДАКТИРОВАТЬ: Сегодня я проверилна моем старом ПК (win10-x64) я получил ту же ошибку, что и на Windows-IoT, поэтому я могу скопировать ее здесь.
