使用 DialogCoordinator 时，Mahapps 中不显示不确定的进度条

Question

当我尝试从 ViewModel 调用 mahapps 进度对话框时：

public async void Test()
{
    var controller =
        await
        this.dialogCoordinator.ShowProgressAsync(
            this, 
            "Progress from VM", 
            "Progressing all the things, wait 3 seconds");
    controller.SetIndeterminate();

    // await Task.Delay(3000);

    // await controller.CloseAsync();            
}

显示了对话框，但对话框底部未显示滚动的不确定进度。使用 Snoop 监视 XAML 显示控件在那里，但栏不显示滚动球。有什么想法吗？

我能够解决问题。添加样式时我只漏了一行：

<ResourceDictionary Source="pack://application:,,,/MahApps.Metro;component/Styles/Controls.xaml" />
<ResourceDictionary Source="pack://application:,,,/MahApps.Metro;component/Styles/Fonts.xaml" />
<ResourceDictionary Source="pack://application:,,,/MahApps.Metro;component/Styles/Colors.xaml" />
<ResourceDictionary Source="pack://application:,,,/MahApps.Metro;component/Styles/Accents/Baselight.xaml" />

<!-- missed the inclusion of accent color style, have own style for anything else so I didn't noticed that -->
<ResourceDictionary Source="pack://application:,,,/MahApps.Metro;component/Styles/Accents/Blue.xaml" />

<ResourceDictionary Source="pack://application:,,,/MahApps.Metro;component/Styles/Clean/Clean.xaml"/>
