  <li>Solution may be near.  Please hold on suggestions for one day.  In
  response to the comment below. I have renamed original VS2017
  Projects Folder as an archive. MSVS2017 creates a new one, perhaps with no     damages. This is beginning to help the problem.  Blank
  Projects now can be deployed.  Moving the original solution folder
  back in failed.  I am trying to execute file triage to get the
  application running again.  This project is relatively small.  Thus
  the cut and paste solution is being attempted.</li>

  <p>An application was running fine for days.  Now deployment fails.</p>
  
  <p>What does the error mean?  How can I correct it?  There is no file name provided.</p>
  
  <p>The only idea I have seen vaguely by searching is to reinstall VS2017.  For lack of time I have not done this yet.</p>
  
  <p>Thanks.</p>
  
  <p>I would like to give more context.  But many things were changed before the application was run again. So I do not want to submit superstitious ideas yet. Close and Open VS2017.</p>
  
  <p>VS2017 gives me this error even if I create a new blank UWP application.</p>
  
  <p>Thanks for your ideas.</p>
