title: How to remove the nuget Packages folder from TFS?
body: <p>I just went through a dll hell. Turns out that TFS has been synchronizing packages, and I ended up with two versions of Microsoft.Web.Optimization and its dependencies at once. NuGet was convinced that I have the newest versions installed, and even reinstallation changed nothing. But at the same time, my projects wouldn't build or, if they'd build, they wouldn't start, complaining that they can't find the library version given in the manifest. </p>
  
  <p>I managed to solve it by uninstalling the packages from NuGet console, physically removing their folders from the hard disc, and then doing a fresh build (which re-installed the missing latest versions). But the package folders I deleted manually are still sitting around in the Source Control Explorer. And I can't delete them, the Delete button is greyed out when I select one of them. I am afraid that they will come again when I get newest version next time. </p>
  
  <p>How do I prevent it? I would like to remove them from the solution completely. In the worst case, it would be OK to ignore them, but as they are on a level above the projects, I can't enter them into a project's .tfignore file, and Visual Studio didn't let me add a .tfignore file to the solution itself. </p>
