Is UserControl dependency property binding broken in Beta 2?

Can anyone confirm or deny this? I cannot seem to find a definitive answer anywhere.

In any case, in Beta 1 this worked� I have a UserControl with a few custom dependency properties defined.

using System.Windows;
using System.Windows.Controls;
using System.Windows.Media;

namespace SilverlightApplication3
{
public partial class SilverlightControl1 : UserControl
{
public SilverlightControl1()
{
InitializeComponent();
}
