在类型 'ResourceDictionary' 中找不到可附加的属性 'MergedDictionaries'

Question

<Application x:Class="mahaapswpf.App"
             xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
             xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
             StartupUri="MainWindow.xaml">
    <Application.Resources>
        <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.MergedDictionaries>
    </Application.Resources>
</Application>

我正在尝试使用 MahApps.Metro 框架，我应该将其包含在我的 App.xaml 中，但我收到 "Nested properties are not supported: ResourceDictionaries.MergedDictionaries" 错误和 "The attachable property "MergedDictionaries " 在类型 "ResourceDictionary" 中找不到。

我已经尝试了所有方法，但仍然无法解决这个问题。任何的想法？谢谢

您缺少实际创建 ResourceDictionary 实例的标签：

<Application.Resources>
    <ResourceDictionary>
        <ResourceDictionary.MergedDictionaries>
            ...
        </ResourceDictionary.MergedDictionaries>
    </ResourceDictionary>
</Application.Resources>

c#

wpf
