Windows Store 10, Windows Phone 10 check if the application is Preloaded or not

Question

Is there any good way to check to see if the application has been pre-loaded on a device or not?

What I need is to be able to check if the user is using the application which is pre-loaded or if he has downloaded it by himself. Is there a property that I can check? or should I ask the OEM to add a file on the devices or properties that I can check?

Answer 1

Try validating the receipt for the app to tell if it was purchased though the store.
