title: Is it safe to manually generate .appxsym and .appxupload for Windows Store Apps crash analysis?
body: <p>We have an app with a manual packaging process (MakeAppx.exe). We would like to publish this app to the Store including the public symbols files, so that I can download the .cab process dump file for crash analysis (<a href="http://msdn.microsoft.com/en-us/library/windows/apps/xaml/hh967782.aspx" rel="noreferrer">such as described here</a>).</p>
  
  <p>I understand the .appxupload is a zip-file contaning the .appx package and an .appxsym file, which in turn is a .zip file containing the .pdb files (<a href="http://msdn.microsoft.com/en-us/library/hh975357.aspx" rel="noreferrer">also according to MSDN</a>).</p>
  
  <p>Is it safe to manually generate/edit these .appxsym and .appxupload for publishing?</p>
