Answer 1

应用程序窗口应在应用程序末尾具有根视图控制器

您似乎没有设置RootViewController。它在旧版本中工作正常。但是在新版本中，您应该在AppDelegate

中进行设置

public override bool FinishedLaunching (UIApplication application, NSDictionary launchOptions)
{
  // Override point for customization after application launch.
  // If not required for your application you can safely delete this method

  var indexVC = new XXXViewController ();//your viewcontroller
  Window = new UIWindow ((CGRect)UIScreen.MainScreen.Bounds);
  Window .RootViewController = indexVC;
  Window .MakeKeyAndVisible ();

  return true;
}

启动时提示NSInternalInconsistencyException
