TransitionFrame有问题

Question

我正在做一个WP7应用程序。我的问题是过渡框架不接受。我收到了错误

“错误1找不到类型或命名空间名称'TransitionFrame'（您是否缺少using指令或程序集引用？）D：\ Resources \ Windows-phone \ Appcity \ Appcity.Application \ App.xaml。 cs 108 28 Appcity.Application“。

我该如何解决这个问题？ 感谢..

App.xaml.cs中的代码是

private void InitializePhoneApplication()
    {
        if (phoneApplicationInitialized)
            return;

        // Create the frame but don't set it as RootVisual yet; this allows the splash
        // screen to remain active until the application is ready to render.
        //RootFrame = new PhoneApplicationFrame();
       RootFrame = new TransitionFrame();
        RootFrame.Navigated += CompleteInitializePhoneApplication;

        // Handle navigation failures
        RootFrame.NavigationFailed += RootFrame_NavigationFailed;

        phoneApplicationInitialized = true;
    }

右键单击“Solution Explorer”（您的项目）中的引用，单击“Add reference”，然后浏览到Toolkit的dll并添加它。 那应该解决它。 见this page
