Application windows are expected to have a root view controller at the end of application

It seems that you didn't set the RootViewController.It worked fine in old version.But in the new version ,you should set it in AppDelegate

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;
}
