我在 mvc3 razor 中工作，我的项目很快运行正确，但我得到了错误
Error 3 Assembly 'System.Web.Mvc, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' uses 'System.Web.WebPages, Version=2.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' which has a higher version than referenced assembly 'System.Web.WebPages, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' c:\Program Files (x86)\Reference Assemblies\Microsoft\Framework\.NETFramework\v4.0\System.Web.Mvc.dll MvcApplication1
我将 system.web.mvc.dll 和 System.Web.WebPages.Razor 文件从 mvc4 文件夹替换为 mvc3 文件夹。以及 web.config 中的一些更改，它开始正常工作。但现在几天后它向我显示以下错误消息
