Purchasing UWP add-ons of type subscription not supported?

[sjorsmiltenburg]

Bug Information

Version Number of Plugin: 3.0.0-beta
Device Tested On: windows
Simulator Tested On: -
Version of VS: 16.6.0
Version of Xamarin: 16.6.000.1055

Steps to reproduce the Behavior

When purchasing a published add-on of type subscription i keep getting
"Choose another item, This in-app purchase item is no longer available in {appname}"

When reading the docs (https://docs.microsoft.com/en-us/windows/uwp/monetize/in-app-purchases-and-trials) it says that add-ons of type subscription have the requirement to use the 'newer' Windows.Services.Store namespace.

Note To use subscription add-ons, your app must target Windows 10 Anniversary Edition (10.0; Build 14393) or a later release in Visual Studio, and it must use the Windows.Services.Store namespace instead of the Windows.ApplicationModel.Store namespace.

When browsing throuth the sources of this plugin I found that it still seems to use the 'old' Windows.ApplicationModel.Store namespace. Therefore I conclude that using this plugin for this type of add-on is not supported.

Is this correct?

Are there plans to move to the new namespace?

I am having the same challenge. Am I missing something? This is the code
var connected = await billing.ConnectAsync(ItemType.Subscription);
string payload = "";
if (!connected)
{
lb_ErrorOccurred = true;
ls_ReturnMessage = AppResources.AppStoreNotAvailableForPurchases;
}
else
{
//purchase the item
var purchase = await billing.PurchaseAsync(ps_ProductId, ItemType.Subscription, payload);

FYI - I have my subscription configured in the Microsoft store as "Available for purchase from within the parent product only.". Do I need to change the store connection type to InAppPurchase instead of Subscription?

[gceaser]

I tried switching both to InAppPurchase and still the purchase object comes back null.

@gceaser I ended up not using this library for UWP purchases and made my own implementation.

@sjorsmiltenburg assuming you got it all working, could you look at my stack overflow post about the native implementation and the problems I am having. Any suggestions you could offer would be appreciated..
