One advantage of this new Universal Apps is I can now forget about having a solution that contains all the various project types I want to support that includes WP7, WP8 and Windows (Modern / Store / Metro),
I will now have just a solution for WP7 and everything else will be done in a solution that contains the Shared Universal App stuff. I still have some details to work out such as what method to share code that isn't platform dependent, play with the bits for a while, but life should be simplified.
It is perhaps because I only have a WP7 device that I remain committed to a WP7 version of my app. By the way, my surface tablet has got me spoiled for high resolution screens and my current phone is inadequate in this regard. My next phone will definitely have a big screen.
I was pleased that I could do phone development in the Windows development visual studio and not have to use the VS Express for the phone separately. I experimented on my laptop though that doesn't have Windows Pro, so the emulator couldn't run. I'll try on my secondary Desktop Dev machine later. My Surface Pro machine doesn't have enough storage space (128 GB) to install all the Visual Studio stuff, so it remains as my WP7 dev machine.
