Answer 1

This problem can be related to re-use of the same app template on Windows Phone (does not affect Windows desktop apps). In the Windows Phone section of the solution explorer, find your app manifest file (Package.appxmanifest), and review the following line near the top of the file (#'s in this example are representative, not actual):

If you have re-used the same app template, then the PhoneProductId number must be different from one iteration to the next. I suggest simply iterating the last digit in the string (e.g., change 1 to 2, or 2 to 3, etc....). Once you make certain all your Windows Phone apps have individualized values in this field, you should be able to deploy them all independently.
