I'm done w/ my game... I've exported it out Windows (Universal app)... opened it in VS 2013, updated the Package Manifest, etc. But, I don't see any XAML files that can be modified w/ your example code in post 2 above... am I missing something? I only see a few .js files and html files. I'm trying to figure out how to put in the Windows Phone 8.1 ad banner to my game as well. After that, it can be published to the Windows Phone Store.
