I have made a linear PathListBox with color Rectangles with this code :

<Path x:Name="path" Data="M20.333333,280.16667 C20.333333,280.16667 315.167,48.666323 620.33367,279.33299" HorizontalAlignment="Left" Height="295.636" Margin="142.563,365.031,0,0" Stretch="Fill" Stroke="Red" StrokeThickness="2" VerticalAlignment="Top" Width="1022" Grid.Column="1"/>

</ec:PathListBox.LayoutPaths>
<Rectangle Fill="AliceBlue" Height="72" Stroke="Red" StrokeThickness="2" Width="70"/>
<Rectangle Fill="#FFA7E4E4" Height="79" Stroke="Red" StrokeThickness="2" Width="77"/>
<Rectangle Fill="Coral" Height="77" Stroke="Red" StrokeThickness="2" Width="74"/>

</ec:PathListBox>
</Grid>
It looks like that :
Excuse my newbiness but I wanted to use the library posted in this subject http://expressionblend.codeplex.com/releases/view/44915 which is the PathListBoxUtils for Blend 4. I am using the new Blend for Visual Studio 2013 update 4, and I have naively tried to make the assembly work in my version. But when I try to use PathLayoutItemTransformer, it is not working under .NET 4.5.1 (which is my current build framework), but working fine under .NET 4 obviously.
Is there a way to port the library to 4.5.1, or maybe use only the classes needed? Or do I have to search for an alternative to my PathListBox?
I think I am a bit lost and I hope this silly mistake could help someone else get to the answer. What I have done is simply get the source code here : Source code of Expression Blend Samples. From there, I simply imported the classes in which I was interested and changed the Framework built to 4.5. Controls and Behaviors magically appeared in Blend and I was able to use the classes fully. Anyway, sorry for the bother.
EDIT : I have another trick that might help someone. I had changed the target CPU to x64, which is why I did not see the prope design in Blend. Changing it back to x32 helped me see the design.
