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能帮助我。问题是：

我最近开始玩MVVM（也是WPF的新手，这是所有这些的学习曲线），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>

我所有的观点都很有说服力，一切看起来都很好。我惊讶于没有MVVM（或MVC）经验的人能够如此轻松地启动和运行。然后我遇到了MetroToolkit需要合并资源字典的问题，现在无论我做什么，我都无法让VS在App.xaml中再次找到我的ViewModelLocator。以下是新标记：

<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>

我试着给资源字典一个键，在区域外添加一行（上面和下面-会出现严重且毫无帮助的错误），但无法让它找到我的VM定位器。当我从App.xaml中删除块时，它会立即工作，但基于我对WPF的有限了解，如果我想让样式对应用程序中的所有视图都可用，我需要这些样式。

有什么想法吗？这已经让我发疯好几个小时了。

是的。。。我前几天刚刚看到这个。。。你必须在里面放一本资源字典。。。

    <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>

**EDIT Sorry...Fixed it now...I was going from memory...this is the way it is in mine.

<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>

            </ResourceDictionary.MergedDictionaries>
        </ResourceDictionary>
