c# - WinRT ContentControl 的 Windows Phone 等效项

Question

我正在尝试将自定义内容控件类从 WinRT 应用程序移植到 Windows Phone 8 应用程序，但我无法弄清楚如何完成它。我基本上想移植如下内容：

菜单面板.cs

public sealed class MenuPanel : ContentControl
{
    #region ContentVisibility

    /// <summary>
    /// ContentVisibility Dependency Property
    /// </summary>
    public static readonly DependencyProperty ContentVisibilityProperty =
        DependencyProperty.Register(
            "ContentVisibility",
            typeof(Visibility),
            typeof(MenuPanel),
            new PropertyMetadata(Visibility.Visible, null));

    /// <summary>
    /// Gets or sets the ContentVisibility property
    /// </summary>
    public Visibility ContentVisibility
    {
        get { return (Visibility)GetValue(ContentVisibilityProperty); }
        set { SetValue(ContentVisibilityProperty, value); }
    }

    #endregion

    ... Lots more, but truncated for brevity
}

泛型.xaml

                            </StackPanel>

                </ControlTemplate>
            </Setter.Value>
        </Setter>
    </Style>
</ResourceDictionary>

主页.xaml

    ...
    <local:MenuPanel Name="MainMenuPanel" Width="520" VerticalAlignment="Center">
        <StackPanel>
            <StackPanel Name="StartMenu" Visibility="Visible">
                <Button Name="NewGameButton" Content="New Game" HorizontalAlignment="Stretch" VerticalAlignment="Stretch" BorderBrush="Transparent" FontSize="30" />
                <Button Name="LoadGameButton" Content="Load Game" HorizontalAlignment="Stretch" VerticalAlignment="Stretch" BorderBrush="Transparent" FontSize="30" />
                <Button Name="OptionsButton" Content="Options" HorizontalAlignment="Stretch" VerticalAlignment="Stretch" BorderBrush="Transparent" FontSize="30" />
            </StackPanel>
        </StackPanel>
    </local:MenuPanel>
    ...

我看了一下http://msdn.microsoft.com/en-us/library/windowsphone/develop/system.windows.controls.contentcontrol(v=vs.105).aspx但它没有多大帮助。
