在我的 web.config 文件和应用程序中，我引用 System.Web.WebPages.Razor v1.0.0.0:

  <dependentAssembly>
    <assemblyIdentity name="System.Web.WebPages.Razor" publicKeyToken="31bf3856ad364e35" culture="neutral" />
    <bindingRedirect oldVersion="0.0.0.0-1.0.0.0" newVersion="1.0.0.0" />
  </dependentAssembly>

我什至不知道是否可以将 System.Web.WebPages.Razor v2.0.0.0 与 .Net 4 一起使用。

现在，我如何找出引用 System.Web.WebPages.Razor v2.0.0.0 的内容？

就这么简单。在 Nuget 包管理器控制台中:

更新包 Microsoft.AspNet.Mvc - 重新安装
