I have a UWP app and a WPF console app for special SDK (can't work in UWP). Linked these apps with default bridge (aka FullTrust). Then I package them with default package project for Windows apps.
But when I tried to upload my .msixupload file to Submission in Microsoft Store, I got this message:
Package acceptance validation error: We encountered a fatal error while parsing the package: Value cannot be null. Parameter name: source. Try again or upload a new package. Screenshot of error
Apps works fine in release. But can't upload a store.
