Public Shared Function RequestAppPurchaseAsync (includeReceipt As Boolean) As IAsyncOperation(Of String)
Determines if this method should return the receipts for this app.
If the includeReceipt parameter is set to true, this string contains XML that represents all receipts for the app and any in-app purchases. If includeReceipt is set to false, this string is empty.
This method returns a success value even if:
- No network connection is available.
- The user cancels out of the dialog.
- The user's authentication fails.
You should treat a success result as indicating the async process completed without errors. To ensure that the transaction itself was successful, check the LicenseInformation element in the returned receipt.
