I'm currently still learning VB 6.0 but red a thread about Option Strict On/Off

As I'm currently writing a application to manipulate acad drawings through the acad object library. I'm seriously late binding to avoid version problems.
(i.a.w. it is suppose to run fine with every Autocad version release 14 upward)

As I was reading a disscussion in VB.net where late binding was qualified as bad coding....
I was wondering how do you overcome this version problem in .net without late binding?
