Have couple questions about how works Windows Store experiments:
Preinstalled apps. No signing with ms account. No internet connection.
Which data expected in this case for user? The local default data(see example) or default data that point at store's experiment at the release moment?
ex: value = _variation.GetString("buttonBackgroundColor", "#FFA3A3A3")
How Store's experiment identity the app? by device? by ms account? Or how app take part at statistics?
