The news told me that a new release of Windows Phone Developer Tools has been released recently. To not copy all the lines down here of what's new in this release, here is the short and simple page to see it.
It's always nice to move on with newer stuff, isn't it? At least it is for me, so I immediately downloaded the installer from here to see what's in there. And.... boom! The screen that I get tells me it's time to go to bed:
Requires removing all my environment to proceed. Disappointment!
So I decided I should wait until I can update the tools on my machine and not install them from scratch. All in all we're busy people and uninstalling and reinstalling a whole bunch of environment (furthermore if that's going to happen once a month) does not sound very attractive.
