Trial app and in-app purchase sample

This sample demonstrates how to perform in-app feature or product purchases operations and use the licensing API provided by the Windows Store to determine the license status of an app or a feature that is enabled by an in-app purchase.

The sample app shows the different ways the licensing API can be used to perform the following tasks for an app.

• Check the current license status of an app
• Check the expiration date of a trial period
• Check if an app's feature has been purchased through an in-app purchase
• Perform an in-app purchase to buy the app
• Perform an in-app purchase to buy an app feature or product
• Perform an in-app purchase transaction using the Windows Store commerce platform.
• Perform an in-app purchase to buy an app feature or product from a large purchase catalog.
