When performing an in-app purchase from a WPF Desktop Application using StoreContext.RequestPurchaseAsync() from the namespace Windows.services.Store, I get a StorePurchaseResult with an ExtendedError message "Value does not fall within the expected range."

I have already submitted the issue on this forum and on ***, but I am still waiting an answer.

The application is published and available for download from the Windows Store.

It was converted using the DesktopAppConverter tool. The manifest.appx was set according to the description in the Store (Identity Name, Publisher...). I followed the instructions provided below for using in-app purchase in C# from the UI thread of a Windows desktop application that uses the Desktop Bridge.

Hello,

Sorry for the delay response.

When we consulted related team about this issue, we got this:

In this case it is an "E_INVALIDARG".  The failure is coming from the token broker trying to get the user’s sign in data.  

And the only likely cause of this error is the HWND is invalid. 

Hope this helps.

Best Regards.
