- Verifying purchases using receipts
In some situations, you may need to verify that a user made an in-app purchase. For example, imagine a game that offers downloaded content. If the user who purchased the content wants to play the game on another PC, you need to verify that the user purchased the content.
- Marketing your app
In addition to articles on how to create a great app listing in the Windows Store, you can get Windows Store logos, usage specifications, and other marketing assets.
