覆蓋成員時違反了繼承安全規則：'System.Data.Entity.Utilities.TaskExtensions

Question

以前，我的網站正在工作，但後來我將GoDaddy ASP.NET設置從vb更改爲c＃。我不記得改變別的。現在，我收到此錯誤：

Server Error in '/' Application. 

Inheritance security rules violated while overriding member: 'System.Data.Entity.Utilities.TaskExtensions+CultureAwaiter`1<T>.UnsafeOnCompleted(System.Action)'. Security accessibility of the overriding method must match the security accessibility of the method being overriden.

這裏是哪裏發生錯誤的代碼，其中第14行是 「HeroicAutoMapperConfigurator」：

[assembly: WebActivatorEx.PreApplicationStartMethod(typeof(HeroicCRM.Web.AutoMapperConfig), "Configure")] 
namespace HeroicCRM.Web 
{ 
    public static class AutoMapperConfig 
    { 
     public static void Configure() 
     { 
      //HeroicAutoMapperConfigurator.LoadMapsFromCallerAndReferencedAssemblies(x => x.Name.StartsWith("YourPrefix")); 
      HeroicAutoMapperConfigurator.LoadMapsFromCallerAndReferencedAssemblies(); 
     } 
    } 
} 

的代碼是從這個項目：

我沒有改變我的應用程序中的任何代碼。有沒有人有什麼建議？

Answer 1

在GoDaddy，他們表示完全重建了我的帳戶，儘管我不確定這意味着什麼。另外，我重新將我的網站從Visual Studio發佈到生產Web託管帳戶，這些事情一起解決了這個問題。

Answer 2

問題與信任級別有關。大多數共享主機不提供完全信任託管。即使您在啓動時使用Microsoft.Owin.Security，也不能使用它。

<appSettings> 
    <add key="owin:AutomaticAppStartup" value="false" /> 

所以最好改變主機，否則你會修改你的代碼。
