title: VSIX - How to include XML documentation files in package?
body: <p>I've found the following article that nicely describes how PDB files of project references can be included in the VSIX package: <a href="http://www.cazzulino.com/include-pdbs-in-vsix.html" rel="nofollow noreferrer">http://www.cazzulino.com/include-pdbs-in-vsix.html</a>.</p>
  
  <p>Now I would like to do the same, but for documentation XML files that are generated by project references. I see that the XML files are already copied to the output directory of the VSIX project, but how can I make sure that they are added to the .VSIX file as well?</p>
