title: How do i automate adding a "using" statement to every files in a folder, namespace or project with Visual Studio 2005 / resharper
body: <p>I am using resharper to do a big refactoring and i keep going from file to file and adding the same namespace over and over again in the "using" section</p>
  
  <p>is there anyway to add a "using" statement to every single file in a folder, namespace or project?  Even though some files wont need the reference, most do, so it will save lots of time.</p>
