I've built a Html5/WinJS app and it's published in the store. I'd like to continue development on it, but in C#/XAML. If I want to resubmit future releases under the same application manifest/appID, whats the easiest way to:
a) Start new project in c# and migration my application identification information over
b) Resubmit the new app and have the store recognize it as the same application with the new codebase as a "1.0X" release.
