Не удалось загрузить файл или сборку «System.Web.Mvc» или одну из его зависимостей

Question

У меня есть это новое приложение MVC, которое я установил на Windows 2008 Server. И получите следующее сообщение, когда я запустил localhost.

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

И в web.config я определил эту сборку,

Может ли один помочь? Смотрите сообщение об ошибке ниже:

Answer 1

не удалось загрузить файл или сборку «System.Web.Mvc, Version = 3.0.0.0, ...»

Ваше приложение использует MVC3, но в соответствии с вашим собственным комментарием, сервер имеет MVC2 (2.0. 50217.0).

Answer 2

У меня была эта проблема при развертывании на сервере, на котором запущен MVC2, файлы, которые необходимо 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 сделал хороший пост здесь (для того, как решить, если вы столкнулись с этой проблемой при развертывании)

Answer 3

Если у вас есть права, чтобы сделать это, вы можете download и установить MVC3 на вашем веб-сервере.

Answer 4

Щелкните правой кнопкой мыши по System.Web.Mvc в своей справочной папке и убедитесь, что для локальной копии установлено значение true. Это должно добавить System.web.mvc в папку bin, и это должно устранить проблему.

Answer 5

Щелкните правой кнопкой мыши на Project -> Управление NuGet Пакеты для решения, чем обновить

Microsoft.AspNet.Mvc и Microsoft.Net.Compilers
