title: How to disconnect project solution from TFS in Visual Studio 2017 or 2019?
body: <p>I have a solution which was connected with TFS. Whenever I try to install new library in the solution, I get an error: </p>
  
  <blockquote>
    <p>Unauthorised (410) </p>
  </blockquote>
  
  <p>I have tried to delete all TFS-related files from solution, but I'm still getting that same error.  </p>
  
  <p>Has anyone faced the same issue and resolved it somehow?</p>
