I'm kinda new at this., so bear with me.
I don't know how to over come this message. I have included a reference to AdMgd & AcDbMgd. I have a line at the top of my class that reads:
Imports Autodesk.AutoCAD.ApplicationServices
I used the VS2008 wizard for AC2010 to generate a project for ADT2009. I don't know if there is a difference between a class library and a WPF class library. Thinking this might have something to do with it. ??
