MVVM轻量级ViewModelLocator + ResourceDictionaries

Question

我最初在MVVM Light CodePlex页面上发布了这条消息，但还没有听到回应，所以我希望这里的人能帮助我。下面是问题：

我最近开始使用MVVM (也是WPF的新手--所有这些学习起来都很费劲)，在我开始使用CodePlex上提供的MetroToolkit之前，我的ViewModelLocator实例和VS2010的绑定设计时间都运行得很好。在使用这个工具包之前，我有以下几点：

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

我所有的观点都很有约束力，一切看起来都很好。我惊讶于没有MVVM (或MVC)经验的人可以如此容易地启动和运行。然后我遇到了一个需要合并资源字典的MetroToolkit问题，现在无论我怎么尝试，我都不能让VS在App.xaml中再次找到我的ViewModelLocator。下面是新的标记：

<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>    

我试着给资源字典一个键，在区域之外添加行(上面和下面-抛出讨厌的和非常无用的错误)，但是不能让它找到我的VM定位器。当我从App.xaml中删除块时，它会立即生效，但基于我对WPF非常有限的知识，如果我想让我的应用程序中的所有视图都可以使用这些样式，我需要这些样式。

有什么想法吗？这已经让我抓狂好几个小时了。

是的.我刚刚看到另一个day...You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>

**现在编辑Sorry...Fixed它...我从memory...this开始就是我的方式。

<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>
