Is it safe to manually generate .appxsym and .appxupload for Windows Store Apps crash analysis?
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 ( such as described here ). 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 ( also according to MSDN ). Is it safe to manually generate/edit these .appxsym and .appxupload for publishing? Yes. This is fine. As you note, the appxupload's format is documented as being a zip archive
