Nope. They start with market share of all installed windows phone.

Plus they have all the windows desktop/tablet users who could use their app as well.

Well, you're wrong because WP7 is now pretty much dead.

So there's literally no reason to target it, and anything written in C/C++ is only going to run on WP8.

So they've pretty much killed off their already lagging platform in preference for a new lagging platform with 0 installed base.

Microsoft are smoking some serious crack. I'm glad our company didn't spend a second developing for WP. What a clusterf*ck.
