有没有一种方法可以简化WPF和Silverlight中依赖项属性的设置？

    private static DependencyProperty CountProperty;

    public MyWpfUserControl()
    {
        InitializeComponent();
        PropertyChangedCallback countChangedCallback = CountChanged;
        var metaData = new PropertyMetadata(countChangedCallback);
        CountProperty = DependencyProperty.Register(\"Count\", typeof (int), typeof (MyWpfUserControl), metaData);
    }

    public int ItemsCount
    {
        get { return (int) GetValue(CountProperty); }
        set { SetValue(CountProperty, value); }
    }

    private void CountChanged(DependencyObject property,
                              DependencyPropertyChangedEventArgs args)
    {
        // Set the value of another control to this property
        label1.Content = ItemsCount;
    }
