c# - 在 WPF 应用程序 Mahapps 中找不到资源字典

Question

我已经按照文档进行操作，并且该应用程序第一次在我的项目中运行良好。今天为了学习 mahapps 上的一些东西，我下载了 github 上提供的演示，并使用 Nuget 修复了一些丢失的资源，这里也没有问题，一切正常。当我重新打开我的项目时，我看到 UI 的预览显示了经典的 VS 控件而不是 mahapps 的控件，也在 App.xml 文件中这一行:

<Application.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" />

                <!-- accent resource -->
                <!-- change "Cobalt" to the accent color you want -->

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

                <!-- theme resource -->
                <!-- change "BaseLight" to the theme you want -->
                <ResourceDictionary Source="pack://application:,,,/MahApps.Metro;component/Styles/Accents/BaseLight.xaml" />
            </ResourceDictionary.MergedDictionaries>
    </ResourceDictionary>

显示这条消息:

error finding the resource dictionary

发生了什么事？一切都很完美!

您缺少 application.resources 结束标记。这是上面的完整代码:

<Application.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" />

                <!-- accent resource -->
                <!-- change "Cobalt" to the accent color you want -->

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

                <!-- theme resource -->
                <!-- change "BaseLight" to the theme you want -->
                <ResourceDictionary Source="pack://application:,,,/MahApps.Metro;component/Styles/Accents/BaseLight.xaml" />
            </ResourceDictionary.MergedDictionaries>
    </ResourceDictionary>
</Application.Resources>
