Getting a "vspscc could not be found in your workspace, or you do not have permission to access it" error : <p>Today, while trying to publish an app so I could test it, I suddenly got this error message:</p>

<blockquote>
  <p>The item
  D:\ScratchSrc\TryNewReportViewer2017\TryNewReportViewer2017\TryNewReportViewer2017.csproj.vspscc
  could not be found in your workspace, or you do not have permission to
  access it.</p>
</blockquote>

<p>That's a mystery to me, as I've never gotten this before and I was working with this app just last week. Publishing it, too.</p>

<p>I've looked for the .vspscc file. Found it exactly where it said it should be. So, the alternative is that I don't have permissions to it. I don't understand why I shouldn't have permissions to a file on my machine that I created, but whatever. So, how do I get permissions to my own file?</p>

<p>I'm working with VS 2017, TFS 2015 on premise.</p>
