Я использовал Visual Studio для создания веб-API с аутентификацией (индивидуальные учетные записи пользователей).Я не внес никаких изменений в предварительно настроенный проект.Я проверил это, чтобы убедиться, что все работает, используя Postman на моей локальной машине.Затем я опубликовал проект в папку, вырезал и вставил проект на Windows 2008 R2 Server.IIS настроен правильно, и я могу перейти на автоматически сгенерированную веб-страницу с документацией по API.
Когда я отправляю сообщение для регистрации учетной записи, я получаю сообщение «Произошла ошибка».После некоторого поиска в Google мне удалось найти способ получить более качественное сообщение об ошибке.

Судя по ошибке, я могу сказать, что она как-то связана с SQL Server.Я установил несколько разных версий на сервер, и я не могу заставить его работать.Я уверен, что я что-то упускаю, но я не могу найти нужную мне информацию нигде.Может ли кто-нибудь указать мне правильное направление, чтобы решить эту проблему?
Спасибо
