如何强制我的WPF主窗口在XP机器上显示Vista？

using System.Windows.Forms;

public partial class App : Application
{
    protected override void OnStartup(StartupEventArgs e)
    {
        base.OnStartup(e);
        Application.EnableVisualStyles();
        Application.SetCompatibleTextRenderingDefault(false);
        Application.VisualStyleState = System.Windows.Forms.VisualStyles.VisualStyleState.ClientAndNonClientAreasEnabled;
    }
}

using System.Windows.Forms;

public partial class MainWindow : Window
{
    public MainWindow()
    {
        InitializeComponent();
        this.Loaded += MainWindow_Loaded;
    }

    private void MainWindow_Loaded(object sender, RoutedEventArgs e)
    {
        System.Windows.Forms.Application.EnableVisualStyles();
        System.Windows.Forms.Application.VisualStyleState = System.Windows.Forms.VisualStyles.VisualStyleState.ClientAndNonClientAreasEnabled;
    }
}

using System.Windows.Forms;

public partial class MainWindow : Window
{
    public MainWindow()
    {
        InitializeComponent();
        this.Loaded += MainWindow_Loaded;

    private void MainWindow_Loaded(object sender, RoutedEventArgs e)
    {
        System.Windows.Forms.Application.EnableVisualStyles();
        System.Windows.Forms.Application.VisualStyleState = System.Windows.Forms.VisualStyles.VisualStyleState.ClientAndNonClientAreasEnabled;
