Thanks a lot Tony that you share information with us.
This is our problem too when we deliver products to customers.
Your code show us why native NETLOAD command works like a ****.
Most common problems usually are that .NET application is compiled
to different framework than AutoCAD. I think that AutoCAD 2013 is
purely compiled to framework 4.0 and below that are to framework 2.0.
Second problem is that if multiple classes uses commandclass attribute
then usually commands are missing.
Ok, thats all right now and good new year to all!
Cheers
