In MainActivity add

public class MyEntryRenderer : EntryRenderer
{
    public MyEntryRenderer(Context ctx) : base(ctx) {}
    protected override void OnElementChanged(ElementChangedEventArgs<Entry> e)
    {
        base.OnElementChanged(e);
        if (e.OldElement == null)
        {
            var nativeEditText = (EditText)Control;
            nativeEditText.SetSelectAllOnFocus(true);
        }
    }
}

and to the top add :

[assembly: ExportRenderer (typeof (Entry), typeof (MyEntryRenderer))]
