Why would you pay for two OS licences when you've got an OS you're happy with? Sure, you might choose an OS based on the applications available (eg I strongly preferDebian GNU/Linux because of apt-get and xmonad) -- switching OS to use a tool seems like a bit of a stretch though.
If you like the MS toolset, by all means use Windows. But using a vm for especially a gui program (which then interacts poorly with your os ui) seems like a sub-optimal solution?
