When I run my program in debug mode, it runs nicely. Now that I want to upload it to the Windows Phone Store, it creates the App Package, but when running the Windows App Certification Kit, it returns the following error:
General metadata correctness test - failed
with the reason:
In the Winmd-File "myBackgroundPart.winmd" (that's my RunTime Component) there is missing "WindowsRuntime 1.3" or "WindowsRuntime 1.2" in the versionstring. The versionstring of the file is "WindowsRuntime 1.4;CLR v4.0.30319".
My environment is Visual Studio 2015 CTP5. The error message suggests, that my WinRT is too new for Store!? How do I downgrade it then?
Edit
This was an issue with VS2015 CTP5, with the new released CTP6 yesterday it was solved.
