Q:

Windows Phone Store App version upgrade with same reserved app name

I have public windows phone app with version 1.0 for windows 8
  - Now I have to do version upgrade to version 2.0 for the same app and users should get notifications for the same.
 - Should I use the same reserved app name as version 1.0 or use another app name for version 2.0
 - What will happen if I submit app with version 2.0 and the same app name?
 - Do I have to use another app name for next version? Or same app name will work?

A:

You dont need to do anything with the App Name Reservation. The app name should be the same irrespective of the versions/update. 
Your existing users will get notified via Updates only when you update your existing app. And if you reserve a new name(for your version 2) and publish it, it will be published as a new individual app and so your app will not be listed in the Updates List of your existing app users.
