Question

以前，我的网站正在运行，但后来我将GoDaddy ASP.NET设置从vb更改为c＃。我不记得改变其他任何事情。现在我收到了这个错误：

Server Error in '/' Application.

以下是发生错误的代码，其中第14行是＆＃34; HeroicAutoMapperConfigurator＆＃34;：

[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();
        }
    }
}

我还没有更改我的应用程序中的任何代码。有没有人有任何建议？

Answer 1

在GoDaddy，他们说完全重建了我的帐户，但我不确定这意味着什么。此外，我将我的网站从Visual Studio重新发布到生产网站托管帐户，这些事情共同解决了这个问题。

Answer 2

问题与信任级别有关。大多数共享主机不提供完全信任托管。如果你使用Microsoft.Owin.Security，即使你在启动时自己使用它，它也无法正常工作。

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

更好地更改主机，否则您将修改代码。
