Let’s hit the bullet points first:
- Mango Beta Dev Tools requires VS2010 SP1 already installed.
- Applications created using it will not run on a NoDo Device.
- It can run side-by-side of the final WP7 release earlier this year. (So you won’t screw up your dev machine)
- It is a beta and you can’t submit an app using it.
- Visual Basic is now fully integrated into the release, but you need to uninstall VB for WP Dev Tools 7.0 First.
