Silverlight to WPF Porting

Question

Hi, I am trying to port a sample application that I found online here:
http://www.shinedraw.com/3d-illusion/flash-vs-silverlight-3d-image-space/#comment-2085

from Silverlight 2.0 to WPF. I am rather new to both Silverlight and WPF, and I am doubtlessly missing something rather obvious in this type of porting procedure. Here is a link to the project file as I modified it:
