IIRC, When MS said that, it turned out they were really just talking about things like "depricated" keyword and designing the OO polymorphism so that changing one thing won't accidentally break something else (ex: manditory "override" keyword when overriding a base class function). I found it confusing too that they referred to that as "versioning".
