重写成员时违反了继承安全规则：'System.Data.Entity.Utilities.TaskExtensions

以前，我的网站正常运行，但是后来我将GoDaddy ASP.NET设置从vb更改为c＃。我不记得要更改任何其他内容。现在我收到此错误：

Server Error in '/' Application.

这是发生错误的代码，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();
        }
    }
}

我没有在应用程序中更改任何代码。有没有人有什么建议？
