Vererberungssicherheitsregeln beim Überschreiben von Membern verletzt: 'System.Data.Entity.Utilities.TaskExtensions

Question

Zuvor funktionierte meine Website, aber dann habe ich die GoDaddy ASP.NET-Einstellungen von vb in C# geändert. Ich kann mich nicht daran erinnern, etwas anderes geändert zu haben. Jetzt bekomme ich diesen Fehler:

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.

Hier ist der Code, wo der Fehler auftritt, wo die Leitung 14 ist "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(); 
     } 
    } 
}

Ich habe keinen Code in meiner Anwendung geändert. Hat jemand irgendwelche Vorschläge?

Answer 1

Bei GoDaddy sagten sie, dass mein Konto von Grund auf neu aufgebaut wurde, obwohl ich nicht sicher bin, was genau das bedeutet. Außerdem habe ich meine Website von Visual Studio auf den Web-Hosting-Web-Account neu veröffentlicht, was zusammen das Problem behebt.

Answer 2

Das Problem hängt mit dem Vertrauensgrad zusammen. Das meiste Shared Hosting bietet kein vollständiges Trust-Hosting. Wenn Sie Microsoft.Owin.Security verwenden, auch wenn Sie es beim Start selbst einschalten, wird es nicht funktionieren.

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

Also besser ein Hosting ändern, sonst werden Sie Ihren Code ändern.
