为什么我的 Xamarin.iOS 应用始终在 Application 类级别引发其 null 异常？

问：

问题

如果我的代码中的某处存在 null 异常（或各种异常），则 Visual Studio 不会在实际发生 null 引用的地方引发，而是会在此处暂停代码：

public class Application
{
    // This is the main entry point of the application.
    static void Main(string[] args)
    {
        // This is where the application breaks on exception
        UIApplication.Main(args, null, "AppDelegate");
    }
}

在编写代码时，我可能应该更加小心，但是当应用程序没有破坏空引用实际发生的地方时，调试问题会非常困难。在这里打破什么也没告诉我。是否有可能解决这个问题？
