title: c# Linq reference unable to load
body: <p>Im unable to add a reference to System.Data.Linq to my project, I get the following error</p>
  
  <blockquote>
    <p>The referenced component
    'System.Data.Linq' could not be found.</p>
  </blockquote>
  
  <p>Even though i added it through the Add reference screen and my other projects add it without issue. This is how it looks in my project</p>
  
  <p><img src="https://i.stack.imgur.com/A7I7c.png" alt="Failed Load"></p>
  
  <p>And this is how it appears in my other project using the same reference</p>
  
  <p><img src="https://i.stack.imgur.com/Qf0SK.png" alt="Added Fine"></p>
  
  <p>Any ideas why this happens, both projects us framework 3.5</p>
  
  <p>Thanks
