主题\ Generic.xaml:

<ResourceDictionary
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
    <ResourceDictionary.MergedDictionaries>
        <ResourceDictionary Source="WPF Commons;component/Controls/Layout/Foo/FooItem.xaml" />
    </ResourceDictionary.MergedDictionaries>
</ResourceDictionary>

控制\布局\富\ FooItem.xaml:

<Style TargetType="{x:Type l:FooItem}">
    <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate TargetType="{x:Type l:FooItem}">
                <Border>
                    <ContentPresenter ContentSource="Header" />
                </Border>
            </ControlTemplate>
        </Setter.Value>
    </Setter>
</Style>

如果我将整个样式复制到我的usercontrol资源中,它可以正常工作.但是,如果我不这样做,则usercontrol显示为空.在Expression Blend 4中,我右键单击并选择Edit Template>,但它不会让我选择Edit a Copy...哪个让我相信某些内容严重错误并且Generic.xaml未正确加载.我认为它是Generic.xaml,因为如果我删除MergedDictionary调用并将xaml样式直接复制/粘贴到Generic.xaml中,它仍然无效.
