I really hope that's tongue in cheek. F'rinstance I make my living now from my own bespoke applications none of which remotely resemble anything that MS offers.
With the sole exception of using MS Word, via COM, to write oodles of reports daily. But as for the applications themselves then, sorry, nothing that Microsoft produces comes close. Other than that I made the mistake of using Visual Studio to write the code in the first place. I wish now that at the time, when the whole process started, that Linux were as it is today.
