c# - 错误 : Inheritance security rules violated by type: 'System.Web.WebPages.Razor.WebPageRazorHost'

Question

我的 ASP.NET MVC 4 解决方案突然给我这个错误:

Inheritance security rules violated by type: 'System.Web.WebPages.Razor.WebPageRazorHost'. Derived types must either match the security accessibility of the base type or be less accessible.

我用谷歌搜索了这个问题，每个人都说当有人将解决方案从一个版本更新到另一个版本时就会发生这种情况。但我没有更新我的解决方案，只是将 IDE 从 VS12 更改为 VS13。这是造成问题的原因吗？

完整的堆栈跟踪如下:

根据我 friend Claudio Redi的评论，这个问题的解决方案是:

尝试删除 web.config 中的 System.Web.Razor 程序集绑定(bind)(如果存在)。 http://forums.asp.net/t/1968686.aspx?Installed+Nuget+package+Razor+Engine+whole+system+stops
