I'm trying to implement in app purchasing for an Avalonia application. I am using the Windows.Services.Store namespace. Whenever I try to use the GetAssociatedStoreProductsAsync method to get information about the product, I get an error code in the ExtendedError of the StoreProductyQueryResult of 0x803F6107.
The application is an Avalonia app with a few projects. In addition to the application projects, there is a Windows Application Packaging Project.
- I have associated the app's packaging project with the store.
- I have created and had approved the store listing for the app.
- I have downloaded the app from the store and run it (this is supposed to get the license info I need to run the app in development according to this page: https://learn.microsoft.com/en-au/windows/uwp/monetize/in-app-purchases-and-trials#testing)
- I have created and had approved a subscription addon.
- The packaging project is the startup project for the solution.
- I have deployed the app (right click the packaging project and press deploy) and then run using visual studio's standard Start Debugging.
Now, some code! Here is where I set up the store context - notice that I am using the Avalonia specific method for getting the window handle - I am unsure if this is the correct method in this context (though I have used this method in other parts of the application to get a handle to successfully launch windows printer driver settings windows)
if (storeContext == null)
{
storeContext = StoreContext.GetDefault();
_context = storeContext;
}
var window = Application.Current?.ApplicationLifetime is IClassicDesktopStyleApplicationLifetime desktop ? desktop.MainWindow : null;
var handle = window.PlatformImpl.Handle.Handle;
WinRT.Interop.InitializeWithWindow.Initialize(_context, handle);
Here is a function I am trying to use to check if the license is valid:
public async Task<bool> CheckIfUserHasSubscriptionAsync()
{
StoreAppLicense appLicense = await _context.GetAppLicenseAsync();
foreach (var addOnLicense in appLicense.AddOnLicenses)
{
StoreLicense license = addOnLicense.Value;
if (license.SkuStoreId.StartsWith(_subscriptionStoreId))
{
if (license.IsActive)
{
return true;
}
}
}
return false;
}
When running this function, the length of AddOnLicenses is always 0 and the function goes straight to the return false.
Here is the function I am trying to use to get the list of products:
public async Task<IEnumerable<StoreProduct>> GetSubscriptionProductsAsync()
{
StoreProductQueryResult result =
await _context.GetAssociatedStoreProductsAsync(new string[] { "Durable" });
if (result.ExtendedError != null)
{
System.Diagnostics.Debug.WriteLine("Something went wrong while getting the add-ons. " +
"ExtendedError:" + result.ExtendedError);
return null;
}
return result.Products.Values;
}
This function returns null with Extended error having a value of 0x803F6107.
Is anyone able to shed any light on this issue?
