Hi,
Here's my resource dictionary for the main application:

ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
    <ResourceDictionary.MergedDictionaries>
        <!--<ResourceDictionary Source="TreeView Resources/StdDataTemplates.xaml"/>
        <ResourceDictionary Source="TreeView Resources/StdTreeViewItemStyle.xaml"/>-->
        <ResourceDictionary Source="pack://application:,,,/GlobalResources;component/Themes/generic.xaml" />
    </ResourceDictionary.MergedDictionaries>
</ResourceDictionary>

This is in the constructor of a class in an assembly referenced by the main assembly:

Style style = (Style)Application.Current.FindResource("StdTreeViewItemStyle");

This works fine at runtime. At design time it doesn't find the resource when using the GlobalResources assemblies resources (but does work if I use the commented version - i.e. additional dictionaries in the main app).
Is there a syntax for the FindResource() that *will* work?
TIA,
Viv
