body: <p>I am getting this error message on one of my development computers:</p>

  <blockquote>
  <p>Assembly File Selector
  The following assembly name can not be resolved automatically.
  System.XML, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null
  Please select the assembly file manually.</p>

  <p>The error is happening on a new computer I just setup. This error does not happen on any of the other computers I have used my program on.</p>
  <p>The program uses .NET Framework 4.8. I have installed that framework on this computer. I am both building my program and running it on this computer.</p>
  <p>Nothing I do with the dialog box seems to matter. My program works fine if press OK or cancel. Selecting a file does not prevent the dialog from appearing again.</p>
  <p>I assume there's some configuration step that didn't happen right on this new computer. What can I do to track down what is going wrong?</p>
