packages.config: нулевой или пустой идентификатор пакета

Я пытаюсь войти в консоль диспетчера пакетов и выдает следующую ошибку:

An error occurred while reading file 'C:\Users\rein.shope\Documents\Visual Studio 2015\Projects\Vidly\Vidly\packages.config': Null or empty package id

Ошибка отображается в виде ленты в верхней части окна. (с кнопкой «Восстановить», которая ничего не делает при нажатии) и красным текстом в окне. Консоль не позволит мне вводить команды.

Содержание packages.config:

Все поля Id кажутся нетронутыми. Поиск Google не возвращает ничего для «нулевого или пустого идентификатора пакета».
