title: Update reference paths for all projects in a solution at once
body: <p>I need to add a reference path to all projects (over 35 projects) in a solution. Doing this manually would be time consuming.</p>
  
  <p>Is there a way to update/add/remove reference paths for all the projects programmatically?</p>
  
  <p>I found an add-in that helps in what I need but unfortunately <a href="http://weblogs.asp.net/mnolton/archive/2006/05/25/Add-In-for-updating-all-reference-paths-in-a-solution.aspx" rel="nofollow noreferrer">the add-in's download link</a> is broken.</p>
