title: Metro App Certification hangs on performance test because of byte code generation
body: <p>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:</p>
  
  <blockquote>
    <p><strong>Following errors were detected when tested the byte code generation:</strong><br>
    This package was made available for the development or Authoringmodus. Uninstall the package and reinstall it in the normal way.</p>
  </blockquote>
  
  <p>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 :(</p>
