title: Unavailable projects in vs 2010?
body: <p>Where does the <em>indication</em> of <em>unavailable or available</em> (loaded) projects / websites  is saved?</p>
  
  <p>I have a solution which has some unloaded projects while <em>only</em> the website is loaded</p>
  
  <p>Of course I can right click and <em>reload it</em> but <em>still</em>, I want to now <em>where</em> this [unavailable or available] info is saved?</p>

  <p>I've been looking in the <code>sln</code>, there is no difference (beyond compare) between loaded one and unloaded one.</p>
  
  <p>Also in <code>Websites.xml</code>, there is no such difference</p>
