How to specify dll search path for xaml located in resource project

Hi

I have some XAML with completion problems

<ResourceDictionary
   ...
   xmlns:ma="clr-namespace;MyAssembly;assembly=MyAssembly"
   >

    <ResourceDictionary.MergedDictionaries>

     <ma:SharedResourceDictionary  Source="pack://siteoforigin:,,/assemblies/WDELConverterResourceDictionary.xaml"> 

// ReSharper says: The name "SharedResourceDictionary" does not exists in the namespace "clr-namespace;MyAssembly;assembly=MyAssembly"

    </ResourceDictionary.MergedDictionaries>

...
I belive this is because Reshaper can't find MyAssembly (as the DLL indeed do contain MyAssembly.SharedResourceDictionary)
For build dependency resons I don't wan't to add a reference to MyAssembly to the project containing the the XAML

is there a way to add an path for resharper to search when it can't find a dll?
