IIS: Microsoft.Web.WebPages.OAuth调用过时的Razor包，导致应用程序崩溃

我最近更新了我的项目从Mvc 3到Mvc 5，我们正试图在IIS服务器上发布应用程序，以便我们可以测试它。但是我们总是有一个严重的崩溃，我不知道是什么引起的，也不知道如何纠正它。

下面是堆栈跟踪:

所以让我困惑的是我们不再安装打包的System.Web.Razor了。相反，我们有System.Web.Razor版本3.0.0.0。尽管如此，我已经完成了这个链接中关于如何从mvc3升级到mvc4的所有建议，并且我的所有软件包都是最新的。

我甚至试图卸载Microsoft.Web.WebPages.OAuth包，看看它是否是原因，但它比蟑螂更有抵抗力，如果没有一个不再编译的应用程序，我就无法删除它。我需要帮助解决这种情况，我唯一的下一个选择是尝试创建一个新的应用程序和重新加载所有的东西，这是有点长和繁琐。
