title: Error when trying to update Extensions in Visual Studio
body: <p>I'm trying to update Extensions in Visual Studio 2010, and I am suddenly getting errors. I open the extension manager and let it load the list of updates. I select one, and click Update, but I get a dialog with an error. One of two errors occurs depending on which extension I am trying to update.</p>
  
  <p>For example, trying to update Nuget gets me:</p>
  
  <pre><code>Value cannot be null
  Parameter name: v1
  </code></pre>
  
  <p>Code Maid, on the other hand:</p>
  
  <pre><code>Invalid entry to install/download
  Parameter name: entry
  </code></pre>
  
  <p>Ankh SVN gives me the same error as Code Maid. (Haven't used or updated Ankh SVN in quite some time, but I tried it to see if it worked)</p>
  
  <p>I am not aware of any recent changes which I have done which could have caused this. The only thing which remotely comes to mind was installing VS11 Beta, but I'm fairly sure I've updated VS2010 extensions since then successfully.</p>
  
  <p>Hopefully, I can avoid the <em>Dreaded Reinstall</em> &trade;</p>

  <p>I appear not to be the only one with this problem:

  <p>Incidentally, I was able to update the extensions in question by downloading and executing the installers manually. But I would still like to know what's going on here, of course!</p>
