Q:

Metro App Certification hangs on performance test because of byte code generation

I try to build a metro-style-app with Javascript and when I run the Windows App Cert Kit (WACK) Certification tool the test always fails on the performance test with the following message:

Following errors were detected when tested the byte code generation:
  This package was made available for the development or Authoringmodus. Uninstall the package and reinstall it in the normal way.

I’m using jquery and some jquery-mobile libraries inside my app. Is that the problem? The error doesn’t make sense for me, because it doesn’t say which package I should reinstall. I also try to uninstall the App itself (by right click onto the app) and build it again in the Release-Modus of VS2012, but the WACK tool always prompts this error :(

A:

Find out that the WACK Tool allways shows this error if you don't run Store -> Create App Package and select "No" and press the next button. After that the WACK-Tool is started automatically and it passes the bytecode generation.
