VSTO Excel 加载项 - WPF XAML 样式问题

Question

我正在创建 VSTO Office Excel-Add-In，其中弹出一个简单的 WPF 窗口。该窗口采用 MahApps 库设计。问题是，无论我使用哪种方法，图标在 Visual Studio 预览中显示良好，但在调试期间它们会丢失。负责显示图标的 Icons.xaml 安装在 Resources 文件夹中，Build 操作设置为 Page。关于这个问题有什么想法吗？

<Controls:MetroWindow.Resources>
    <ResourceDictionary>
        <ResourceDictionary.MergedDictionaries>
            <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/Blue.xaml" />
            <ResourceDictionary Source="pack://application:,,,/MahApps.Metro;component/Styles/Accents/BaseLight.xaml" />
            <ResourceDictionary Source="pack://application:,,,/MahApps.Metro;component/Styles/Controls.AnimatedSingleRowTabControl.xaml" />
            <ResourceDictionary Source="pack://application:,,,/ExcelAddIn;component/Resources/Icons.xaml" />
        </ResourceDictionary.MergedDictionaries>
    </ResourceDictionary>
</Controls:MetroWindow.Resources>

我也尝试过，但没有成功：

<ResourceDictionary Source="/ExcelAddIn;component/Resources/Icons.xaml" />

<ResourceDictionary Source="pack://application:,,,/component/Resources/Icons.xaml" />
