project bug

I have an Entry control.
I try to entry.Focus() but the focus is never set.
I've tried in iOS

Also in Android I don't see any "focus" on entry

you're trying to `entry.SetFocus ()` from the Page constructor. At that time, the page is not on screen and can't be focused reliably.

To get the behavior you expect, invoke `entry.SetFocus ()` from `OnAppearing ()`

	public class PageFocus : ContentPage
		Entry entry;
		public PageFocus ()

			StackLayout sl = new StackLayout ();
			sl.Padding = new Thickness (10, 20, 10, 0);
			entry = new Entry ();
			entry.Placeholder = "ENTRY";

			sl.Children.Add (entry);
			Content = sl;

		protected override void OnAppearing ()
			base.OnAppearing ();
			entry.Focus ();
