No, that's incorrect. FUNCTIONALITY is reuseable when one uses the compiled version of old code, but code is only reuseable when it can be imported into a new project directly.
That is a fundamental programming misunderstanding that you hype above. You have clearly failed to learn the distinction between "code" and "functionality," relatively basic concepts for professional programmers (of which you do not appear to be).
When the only people who say .NET is without problems are it's salemen, I find it's pretty easy to draw a conclusion.
Heck, the very title of the piece is a spin line right up there with 'The Comeback Kid' -- the story says no one is using it but the headline says it "Strikes a chord with programmers".
I love FR.
