c# - 在类型“ResourceDictionary”中找不到可连接属性“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，应该将其包含在App.xaml中，但出现“不支持嵌套的属性：ResourceDictionaries.MergedDictionaries”错误，而没有“可连接的属性“ MergedDictionaries””在“ ResourceDictionary”类型中找到。

我已经尝试了一切，但仍然无法解决。任何的想法？谢谢。

您缺少实际创建ResourceDictionary实例的标记：

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