WPF:DependencyProperty拒绝工作

我试图在一个窗口上注册3个依赖属性来控制它的格式。我一遍又一遍地看了一遍代码,但一定是漏掉了什么。

public static readonly DependencyProperty TextColorProperty = DependencyProperty.Register("TextColor", typeof(Color), typeof(WinStickyFingers), new PropertyMetadata(Colors.White));
public Color TextColor {
    get { return (Color)base.GetValue(TextColorProperty); }
    set { base.SetValue(TextColorProperty, value); }
}

public static readonly DependencyProperty BackgroundColorProperty = DependencyProperty.Register("BackgroundColor", typeof(Color), typeof(WinStickyFingers), new PropertyMetadata(Colors.Black));
public Color BackgroundColor {
    get { return (Color)base.GetValue(BackgroundColorProperty); }
    set {
        base.SetValue(BackgroundColorProperty, value);
    }
}    
<TextBlock DockPanel.Dock="Top" Text="{Binding Name}" Foreground="{Binding TextColor,Converter={StaticResource DebugConverter}}" Background="{Binding Path=BackgroundColor}" />

我正在使用bea-stollnitz的调试方法,但我的断点甚至没有被触发。
