  x:Class="SDKSample.FELoaded"
  Loaded="OnLoad"
  Name="root"
>
</StackPanel>

void OnLoad(object sender, RoutedEventArgs e)
{
    Button b1 = new Button();
    b1.Content = "New Button";
    root.Children.Add(b1);
    b1.Height = 25;
    b1.Width = 200;
    b1.HorizontalAlignment = HorizontalAlignment.Left;
}

Public Sub OnLoad(ByVal sender As Object, ByVal e As RoutedEventArgs)
    Dim b1 As Button = New Button()
    b1.Content = "New Button"
