title: Nuget DisableSourceControlIntegration not working
body: <p>I'm trying to follow the no-commit strategy in keeping assemblies out of TFS while using NuGet.  I'd like the projects to auto-restore dependencies and not add pending changes to TFS. </p>
  
  <p>I've read a few ways to do this; one being using .tfignore, which will be a pain with the number of projects we have.  We could cloak the folder in TFS, but we would need to add the packages folder for every project in order to cloak it.  The last way, is to configure NuGet via NuGet.config using disableSourceControlIntegration which will keep the NugetClient from adding the packages to the project or solution.  </p>
  
  <p>**This is the configuration XML I'm using:</p>
  
  <pre><code>&lt;solution&gt;
  &lt;add key="disableSourceControlIntegration" value="true" /&gt;
  &lt;/solution&gt;
  </code></pre>
  
  <p>If I place it in my {SolutionDir}.nuget folder it works for that solution.  I'm trying to place it in my %AppData%\nuget folder so that it is applied to all solutions but package restore is still causing TFS to add my packages folder contents.</p>
  
  <p>I'm using Visual Studio 2013, NuGet 2.8.6 and TFS from VSOnline.**</p>
