问题
When I create an appx app with VS2013 for Windows Phone, the AppxManifest.xml contains the following two entries:
<Identity Name="Something.Arbitrary" Publisher="CN=GUID-GUID-GUID" Version="1.0.0.0" />
<mp:PhoneIdentity PhoneProductId="5fbbac69-e356-41ee-af0d-0aab0eb96d7c" PhonePublisherId="00000000-0000-0000-0000-000000000000" />
What is the difference between the two Identity Name and PhoneIdentity values?
回答1:
mp:PhoneIdentity is used, if you update your app coming from an older version, e.g. Windows Phone 8.0.
With newer versions, like 8.1 Phone or 8.1 Universal Apps, it creates a new type of application binary and it can't create a link to the old store data. E.g.: If you then test your IAPs, your app won't find the IAP items.
This is done with the values PhoneProductId and PhonePublisherId.
Quoting the docs ( https://msdn.microsoft.com/en-us/library/windows/apps/Dn642081%28v=VS.105%29.aspx ):
The PhoneProductID and PhonePublisherID attributes of the mp:PhoneIdentity element in the Package.appxmanifest file are available to enable these upgrade scenarios. These attributes map to the ProductID and PublisherID attributes of the published Windows Phone 8 app.
