错误:类型违反的继承安全规则:'System.Web.WebPages.Razor.WebPageRazorHost'

Question

在我的asp.net mvc 4解决方案给我这个错误的地方没有:

违反类型的继承安全规则:'System.Web.WebPages.Razor.WebPageRazorHost'.派生类型必须与基本类型的安全可访问性匹配,或者不太容易访问.

我搜索了这个问题,每个人都说当任何人将这个解决方案从一个版本更新到另一个版本时就已经发生了.但我没有更新我的解决方案,只需将IDE从VS12更改为VS13.这是造成问题的原因吗？

完整堆栈跟踪如下:

Answer 1

从我的朋友Claudio Redi的评论来看,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(如果存在).http://forums.asp.net/t/1968686.aspx?Installed+Nuget+package+Razor+Engine+whole+system+stops

Answer 2

转到Web.config并搜索程序集名称="System.Web.Razor"并注释如下.

 <!--<dependentAssembly>
    <assemblyIdentity name="System.Web.Razor" publicKeyToken="31bf3856ad364e35" culture="neutral" />
    <bindingRedirect oldVersion="0.0.0.0-3.0.0.0" newVersion="3.0.0.0" />
  </dependentAssembly>-->

在评论保存并运行项目后,它将正常工作.
