Я искал ответ, но не смог найти ничего подходящего моей ситуации.

Сайт работает совершенно нормально, когда я запускаю его локально, но когда я публикую его в Azure, если я пытаюсь использовать страницу, обращающуюся к базе данных, появляется следующая страница ошибки:

Server Error in '/' Application.

Вот моя строка подключения с удаленным именем пользователя / паролем / сервером .:

<add name="DefaultConnection" providerName="System.Data.SqlClient" connectionString="Server=<server>;Database=ELO;User ID=<username>;Password=<password>;Trusted_Connection=False;Encrypt=True;Connection Timeout=30;" />

Хотя я не понимаю, почему это будет работать локально, но не в Azure. Сайт и база данных SQL размещены в одной учетной записи.
