如何绑定到Silverlight 4中的单例属性？

public class Singleton
{
    private static Singleton instance;

    private Singleton()
    {
        // 私有构造函数，防止外部实例化
    }

    public static Singleton Instance
    {
        get
        {
            if (instance == null)
            {
                instance = new Singleton();
            }
            return instance;
        }
    }

    // 其他属性和方法...
}

<TextBlock Text="{Binding Source={x:Static local:Singleton.Instance}, Path=Name}" />

public class Singleton : INotifyPropertyChanged
{
    // ...

    private string name;
    public string Name
    {
        get { return name; }
        set
        {
            if (name != value)
            {
                name = value;
                OnPropertyChanged("Name");
            }
        }
    }

    public event PropertyChangedEventHandler PropertyChanged;

    protected virtual void OnPropertyChanged(string propertyName)
    {
        PropertyChanged?.Invoke(this, new PropertyChangedEventArgs(propertyName));
    }

    // ...
}
