AutoCropCommand Method Not Found

I'm using the 14.5 demo version of .net tools in vs2005 / .net 2 / C#

I noticed in the CSMainDemo example, there is an autocropcommand implemented that I would like to make use of.  I've written a simple app that scans an image, on the acquirepage trigger I am attempting to first pass the image through the autocropcommand and then save it out.  When the autocropcommand runs, I get an exception as follows.  I am almost certain that I am not referencing something properly, but for the life of me I can't figure out what it needs to be or what needs to be set in code for this to work.  Can anyone point me in the right direction?

Thanks in advance!
