title: In App Purchase Windows Store Apps
body: <p>I used CurrentApp object to perform an In-app purchase in my application. The process worked fine and users successfully purchased different features. I had to give an update for the app, after a few bug fixes. After the update the users that had bought features through in-app purchase are complaining to have lost previously bought features. How does windows store persist the purchases? Do I need to manually store all transaction details within the app as well?</p>
