Не удалось загрузить файл или сборку 'System.Web.Mvc' или одну из ее зависимостей

Question

У меня есть это новое приложение MVC, которое я установил на Windows 2008 Server. И получаю следующее сообщение при запуске localhost.

Я проверил папку Bin и могу подтвердить, что System.Web.MVC там. И версия файла, 2.0.50217.0

А в web.config я определил эту сборку,

Может ли кто-нибудь помочь? Смотрите сообщение об ошибке ниже:

Answer 1

У меня была эта проблема при развертывании на сервере, на котором работал MVC2, файлы, которые нужно будет включить в сборку:

Microsoft.Web.Infrastructure.dll
System.Web.Helpers.dll
System.Web.Mvc.dll
System.Web.Razor.dll
System.Web.WebPages.Deployment.dll
System.Web.WebPages.dll
System.Web.WebPages.Razor.dll

Фил Хаак написал здесь хороший пост (о том, как решить, столкнулись ли вы с этой проблемой при развертывании)

Answer 2

Не удалось загрузить файл или сборку 'System.Web.Mvc, версия = 3.0.0.0, ... "

Ваше приложение использует MVC3, но, согласно вашему собственному комментарию, на сервере установлен MVC2 (2.0.50217.0).

Answer 3

Щелкните правой кнопкой мыши на Project -> Управление пакетами Nuget для решения, отличного от обновления

Microsoft.AspNet.Mvc и Microsoft.Net.Compilers

Answer 4

Если у вас есть права на это, вы можете загрузить и установить MVC3 на свой веб-сервер.

Answer 5

Щелкните правой кнопкой мыши System.Web.Mvc в вашей справочной папке и убедитесь, что для параметра local local установлено значение true. Это должно добавить System.web.mvc в папку bin, и это должно исправить проблему.
