Xamarin.Forms (WinPhone) Hide the Title space NavigationBar for Xamarin.Forms.NavigationPage. Please

Question

In App.cs, when I set the Main page = new MyContentPage(). It is doing good. However, I have to do Navigation.PushAsync(somePage()), so when I changed Main page = new NavigationPage(new MyContentPage()) it comes out with a huge title space, which I don't want that. Please help me to hide that. Thanks.

UPDATE:
I've tried NavigationPage.SetHasNavigationBar(this, false) is not working to me. Can I know which version of Xamarin.Forms is working for SetHasNavigationBar(this, false) ? I've tried both Xamarin.Forms 2.0 and the latest 2.3 and they are both seem not responsive to WinPhone.
Is there anyway I can modified it in WinPhone Independent API?

My code:

public class App : Application
{
    public App()
    {
        NavigationPage.SetHasNavigationBar(this, false);
        MainPage = new NavigationPage(new CP());
        NavigationPage.SetHasNavigationBar(this, false);
    }
}

You can remove the title bar of your NavigationPage by calling: NavigationPage.SetHasNavigationBar(this, false);
