Hello friends, I was raised a doubt, if you wanted, you could have installed VisualStudio 2008 and VisualStudio 2012? ... are incompatible to have them together?
You can have both of them on the same computer I believe but I really don't see the point of having them both since 2012 will have almost everything 2008 has and more.
The only justification for moving off XP is 64bit. In my view, there's no point in running 32bit Windows 7. It's a poor way of controlling a 32bit machine, it takes 25% of the machine to control it.
