How to specify path for file from different project in WPF?

I've got two projects in WPF and one project is the main one and the second one is just for testing (it uses files of the main project - files are added via Project -> add -> Existing items... -> selected file -> add as link so that the file is only in the main project really).

Folders with projects are these:

C:\Work\...\Projects\Main
C:\Work\...\Projects\XXXTestProject

where XXX stands for different parts of the Main project which I test separately.

I've got the code:

<Window x:Class="Sokoban.Window1"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:local="clr-namespace:Sokoban"
    xmlns:diag="clr-namespace:System.Diagnostics;assembly=WindowsBase"
    Title="Window1" Height="559" Width="419">
    <Window.Resources>        
        <ResourceDictionary>
            <ResourceDictionary.MergedDictionaries>
     开发者_JAVA技巧           <ResourceDictionary Source="GameDesk.xaml" />
            </ResourceDictionary.MergedDictionaries>
        </ResourceDictionary>
    </Window.Resources>

    <Grid>        
        <Rectangle local:GameDeskProperties.FieldSize="30" Name="myrect" Style="{DynamicResource GameDesk}" MouseEnter="Rectangle_MouseEnter" />
    </Grid>
</Window>

... which should use XAML resources from GameDesk.xaml which is in the main project and it seems that I can't use Pack URI (http://msdn.microsoft.com/en-us/library/aa970069.aspx). How can I specify the file?

• Should I use absolute path? (C:\Work...\Main\Resources\GameDesk.xaml)

• Or is there any other way?

Thank you for help!

MSDN link here

Use a pack:// URI of the form:

pack://application:,,,/ReferencedAssembly;component/Subfolder/ResourceFile.xaml

if the XAML is in a referenced assembly

or

pack://siteoforigin:,,,/Subfolder/SiteOfOriginFile.xaml

if the XAML is loose and copied to the bin folder.
