关于Wpf的Fluent Ribbon问题。

Fluent Ribbon 控件是从这里下载的：

我想用代码生成一个RibbonWindow，但找不到怎样添加那个“文件”按钮，请高手帮忙看下，多谢！
我的代码：

namespace Fluent
{
    public class startWindow : RibbonWindow
    {
        public startWindow()
        {
            Grid grid0 = new Grid();
            RowDefinition rd1 = new RowDefinition();
            rd1.MaxHeight = 135;
            RowDefinition rd2 = new RowDefinition();
            grid0.RowDefinitions.Add(rd1);
            grid0.RowDefinitions.Add(rd2);

            Ribbon ribbon = new Ribbon();

            Grid grid = new Grid();
            Grid.SetRow(grid, 1);
            grid0.Children.Add(grid);

            RibbonTabItem rti = new RibbonTabItem();
            rti.Header = "开始";
            ribbon.Tabs.Add(rti);

            grid0.Children.Add(ribbon);
            this.AddChild(grid0);
        }
    }
}

哈哈，方法找到啦！
现公布出来，供养有缘人：

Backstage backstage = new Backstage();
ribbon.Menu = backstage;

BackstageTabControl btc = new BackstageTabControl();
backstage.Content = btc;

Fluent.Button bt1 = new Fluent.Button();
bt1.Header = "新建";
btc.Items.Add(bt1);

BackstageTabItem bti2 = new BackstageTabItem();
bti2.Header = "历史记录";
btc.Items.Add(bti2);

我也正在研究Fluent Ribbon和微软自己的WPF Ribbon，现在微软的Ribbon感觉好多bug啊
