i upgraded from 2010 to 2011 and noticed one minor problem:
Dim pref As AcadPreferences = Autodesk.AutoCAD.ApplicationServices.Application.Preferences
this line throws exception, that i have attached
the issue is, that after installing Civil 2011, libraries in Autodesk Shared directory were replaced with the new ones and somehow 2010 can't hande this
with the old 2010 dlls, this code was fine, also on 2011 this code works good, problem only occures, when i use the build with 2011 references on AutoCAD 2010
