MVVM Light ViewModelLocator + ResourceDictionaries

Question

我最初在 MVVM Light CodePlex 页面上发布了这条消息，但还没有收到回复，所以我希望这里有人可以帮助我。问题来了：

我最近开始使用 MVVM（也是 WPF 的新手——所有这一切的学习曲线都相当不错），在我开始使用 CodePlex 上提供的 MetroToolkit 之前，我的 ViewModelLocator 实例和 VS2010 的绑定设计时一切都很好。在使用该工具包之前，我有以下内容：

<Application.Resources>
    <local:ViewModelLocator x:Key="Locator" d:IsDataSource="True" />
</Application.Resources>

我所有的观点都很好，一切看起来都很好。我很惊讶没有 MVVM（或 MVC）经验的人可以轻松启动和运行。然后我遇到了需要合并资源字典的 MetroToolkit 的障碍，现在无论我尝试什么，我都无法让 VS 在 App.xaml 中再次找到我的 ViewModelLocator。这是新的标记：

<Application.Resources>

        <ResourceDictionary>

            <ResourceDictionary.MergedDictionaries>
                <ResourceDictionary Source="/MetroToolkit;component/Themes/Dark/Colors.xaml" />
                <ResourceDictionary Source="/MetroToolkit;component/Themes/Dark/Animations.xaml" />
                <ResourceDictionary Source="/MetroToolkit;component/Themes/Dark/Geometry.xaml"/>
                <ResourceDictionary Source="/MetroToolkit;component/Themes/Dark/Generic.xaml"/>
                <ResourceDictionary Source="/MetroToolkit;component/Themes/Dark/Buttons.xaml" />
                <ResourceDictionary Source="/MetroToolkit;component/Themes/Dark/Scrollbar.xaml" />
                <ResourceDictionary Source="/MetroToolkit;component/Themes/Dark/Scrollviewer.xaml" />
                <ResourceDictionary Source="/MetroToolkit;component/Themes/Dark/RadioButton.xaml" />
                <ResourceDictionary Source="/MetroToolkit;component/Themes/Dark/ProgressBar.xaml" />
                <ResourceDictionary Source="/MetroToolkit;component/Themes/Dark/ContextMenu.xaml" />
                <ResourceDictionary Source="/MetroToolkit;component/Themes/Dark/Tooltip.xaml" />
                <ResourceDictionary Source="/MetroToolkit;component/Themes/Dark/Checkbox.xaml" />
                <ResourceDictionary Source="/MetroToolkit;component/Themes/Dark/Headings.xaml" />
                <ResourceDictionary Source="/MetroToolkit;component/Themes/Dark/Textbox.xaml" />
                <ResourceDictionary Source="/MetroToolkit;component/Themes/Dark/Combobox.xaml" />
                <ResourceDictionary Source="/MetroToolkit;component/Themes/Dark/Slider.xaml" />
                <ResourceDictionary Source="/MetroToolkit;component/Themes/Dark/Expander.xaml" />
                <ResourceDictionary Source="/MetroToolkit;component/Themes/Dark/TabControl.xaml" />
            </ResourceDictionary.MergedDictionaries>

            <local:ViewModelLocator x:Key="Locator" d:IsDataSource="True" />

        </ResourceDictionary>
    </Application.Resources>    

我尝试为资源字典提供一个键，在该区域之外添加行（上方和下方 - 引发讨厌且非常无用的错误）并且无法找到我的 VM 定位器。当我从 App.xaml 中删除该块时，它会立即起作用，但基于我对 WPF 的非常有限的了解，如果我希望这些样式可用于我的应用程序中的所有视图，我需要这些。

有什么想法吗？这已经让我发疯了几个小时了。

是的...我前几天才看到这个...你必须在里面放一个资源字典...

    <ResourceDictionary>

                <ResourceDictionary.MergedDictionaries>
                    <ResourceDictionary Source="/MetroToolkit;component/Themes/Dark/Colors.xaml" />
                    <ResourceDictionary Source="/MetroToolkit;component/Themes/Dark/Animations.xaml" />
                    <ResourceDictionary Source="/MetroToolkit;component/Themes/Dark/Geometry.xaml"/>
                    <ResourceDictionary Source="/MetroToolkit;component/Themes/Dark/Generic.xaml"/>
                    <ResourceDictionary Source="/MetroToolkit;component/Themes/Dark/Buttons.xaml" />
                    <ResourceDictionary Source="/MetroToolkit;component/Themes/Dark/Scrollbar.xaml" />
                    <ResourceDictionary Source="/MetroToolkit;component/Themes/Dark/Scrollviewer.xaml" />
                    <ResourceDictionary Source="/MetroToolkit;component/Themes/Dark/RadioButton.xaml" />
                    <ResourceDictionary Source="/MetroToolkit;component/Themes/Dark/ProgressBar.xaml" />
                    <ResourceDictionary Source="/MetroToolkit;component/Themes/Dark/ContextMenu.xaml" />
                    <ResourceDictionary Source="/MetroToolkit;component/Themes/Dark/Tooltip.xaml" />
                    <ResourceDictionary Source="/MetroToolkit;component/Themes/Dark/Checkbox.xaml" />
                    <ResourceDictionary Source="/MetroToolkit;component/Themes/Dark/Headings.xaml" />
                    <ResourceDictionary Source="/MetroToolkit;component/Themes/Dark/Textbox.xaml" />
                    <ResourceDictionary Source="/MetroToolkit;component/Themes/Dark/Combobox.xaml" />
                    <ResourceDictionary Source="/MetroToolkit;component/Themes/Dark/Slider.xaml" />
                    <ResourceDictionary Source="/MetroToolkit;component/Themes/Dark/Expander.xaml" />
                    <ResourceDictionary Source="/MetroToolkit;component/Themes/Dark/TabControl.xaml" />
 <ResourceDictionary>
                     <local:ViewModelLocator x:Key="Locator" d:IsDataSource="True" />
                </ResourceDictionary>
                </ResourceDictionary.MergedDictionaries>

        </ResourceDictionary>

**编辑 抱歉……现在修好了……我是从记忆中走出来的……这是我的样子。

<ResourceDictionary>
            <ResourceDictionary.MergedDictionaries>
                <ResourceDictionary Source="Dictionaries/converters.xaml" />
                <ResourceDictionary Source="assets/styles.xaml" />
                <ResourceDictionary Source="assets/sdkstyles.xaml" />
                <ResourceDictionary Source="assets/corestyles.xaml" />
                <ResourceDictionary>
                    <local:ApplicationResources x:Key="ApplicationResources" />
                </ResourceDictionary>
