[Solved] In-App purchase in Windows Store Apps? (8.1)

Hi community,

I was having problems getting In-App purchase working in my game on the Windows Store App (8.1) platform, but I think I got it working. Wanted to post my solution in case it helps anybody.

Normally I try to make all the 'async' APIs run synchronously by using the "Task.Run(async () => { my function }).Wait()" code, however in WP8, the marketplace would not appear unless I ran it like this:

Code (CSharp):

1.  
2.                 System.Windows.Deployment.Current.Dispatcher.BeginInvoke(
3.                     async () =>
4.                     {
5.                         try
6.                         {
7.                             string receipt = await CurrentApp.RequestProductPurchaseAsync(productListing.ProductId, true);
8.  

All Windows examples have the purchasing done from the UI thread.. it seems like the dispatcher has to be used when trying to make a purchase, so I also imitated this in my WSA implementation.

Code (CSharp):

1.  
2. #elif NETFX_CORE
3.         Task.Run(
4.             async () =>
5.             {
6.                 await CoreApplication.MainView.CoreWindow.Dispatcher.RunAsync(
7.                     CoreDispatcherPriority.Normal,
8.                     async () =>
9.                     {
10.                     PurchaseResults result = await CurrentApp.RequestProductPurchaseAsync(productID);
11.                     switch(result.Status)
12.                     {
13.                     case ProductPurchaseStatus.Succeeded:
14.                         await CurrentApp.ReportConsumableFulfillmentAsync(productID, result.TransactionId);
15.                         OnPurchaseDismissed(productID);
16.                         break;
17.                     case ProductPurchaseStatus.NotFulfilled:
18.                         InAppPurchaseManager.Instance.CheckUnfulfilledConsumables();
19.                         await CurrentApp.ReportConsumableFulfillmentAsync(productID, result.TransactionId);
20.                         OnPurchaseDismissed(productID);
21.                         break;
22.                     }
23.                 });
24.             }).Wait();
25. #else
26.  

Now its trying to reach out to marketplace, but fails since my app isn't listed. But at least its getting the marketplace involved.. I think it will work after I update/re-list my game.

 

The SOOMLA Store in-app purchase plugin just released an updated version that supports Windows Phone 8 in-app purchases out of the box.
