title: how to troubleshoot "Error HRESULT E_FAIL has been returned from a call to a COM component" when Updating Service Reference
body: <p>I have a WCF Service that I'm trying to write a client for.  When I add a service reference there is no problem.  If I update the reference, I receive the &quot;Error HRESULT E_FAIL has been returned from a call to a COM component&quot; error.  My service is running (not in debug mode).  I have two main questions on this, and so far I haven't been able to find out much from my research.</p>
  <ol>
  <li>What exactly does this error mean?</li>
  <li>How can I begin troubleshooting the issue?  I don't have enough information, but I don't know where to look to find any logs or data related to the issue.</li>
  </ol>
  <p>For my service, this is only happening in Visual Studio 2017 and 2019.  If I create a client in 2015 and update the reference, there is no problem.</p>
  <p>Thanks for any help in figuring out how to track this down.</p>
