WPF: How to Plot Controls to Show Up in Toolbox?

Hi Everyone,
I am amazed. This plot looks to be very well done. I am looking forward to using it. It is compiling and running well (just needed to update Nuget package and to be sure I ran update 3 of VS 2012 Express).

I hope this last hurdle is pretty small. Wondering, how do I get the controls to show up in the toolbox? I tried finding a dll or ?? where they were located by right clicking on "All WPF Controls" and selecting "Choose Items..." but could not find anything. Note that I installed OxyPlot.WPF using Nuget through VS.

Thanks,

Alan
