Yes, you need Acad2006 for the app being built on Acad2006.NET API.
The general rule from AutoDesk on this kind of version issue is app built on
earlier version would run on later version, not the other way around.

I have 2005 .Net API and I am using it in my first project (Visual Studio
2003). However, as you mentioned, it is not as comprehensive as .Net 2006
API. For this reason I wanted to try the latest one.
So, my question remains; do I need autocad 2006 on my machine to run
applications developed using 2006 .Net API?
Thanks for yor reply.
