我正在尝试将 AutoMapper 集成到我的 Xamarin Forms 应用程序中。它在 Android 设备和模拟器中都能成功运行，但在 iOS 中我只能让它在模拟器中运行。在真实设备上运行它会导致 System.ArgumentNullException。
这是我的 App.xaml.cs OnStart 方法中的 Mapper.Initialize 代码：
// AutoMapper config
Mapper.Initialize(cfg =>
{
cfg.AddProfile<MappingProfile>();
});
这是堆栈跟踪：
System.ArgumentNullException: Value cannot be null.
