RibbonCommand Missing

Aug 19, 2010 at 11:08 PM

I'm using the latest release of the Ribbon Preview from MS Downloads (3.5.40729.1).

I've included the proper assemblies, and I have a Ribbon up and running, but I'm trying to look at using commands now.

Whenever I try and create a RibbonCommand in xaml or code, it can't find it.  Has it been removed?  What's the proper way to re-use objects and utilize the QAT now?

I also just downloaded the Checkbook Example App which is also using the RibbonCommand and it won't compile now with the new version.
