I have an application X in the Microsoft store for testing.
To get some experience with the Windows.Services.Store I tried the Microsoft Store sample and I associated the App with the store application X. The Store sample worked fine.
Next I extended my app with a purchase function and associated this app also with the store application X. In debug mode it worked correct, but the release mode gave the error:
Internal compiler error: An item with the same key has already been added.
Is the reason for the error that I have associated two apps with the same store application? Anyway, how to correct this error?
