title: Project requires reference to Entity Framework but it shouldn't
body: <p>I'm fighting a weirdly unexpected issue with references. There are two two projects: <em>Model</em> and <em>Handler</em>. The former has a reference to EF (as it should) and so does the latter. Of course, <em>Model</em> provides the model information and it's referenced by <em>Handler</em>.</p>
  
  <p>Obviously, it seems to be unnecessary to have a reference to EF in <em>Handler</em>, as it should get it's knowledge about it via the referenced <em>Model</em> project. So I removed the references to EF from it.</p>
  
  <p>To my surprise, VS barked at me and demanded EF to be referenced in <strong>both</strong> the projects! Why is it so and is it supposed to be like that?!</p>
  
  <p>Please note that removing the references to both <em>Model</em> and EF makes the names of the classes in defined in my model red (as supposed to) and referencing <em>Model</em> back into <em>Handler</em> turns them green. However, even then, I get this red underline requiring me to reference EF too. I don't get it...</p>
