title: The type or namespace name 'DbContext' could not be found (EF installed)
body: <p>I am using VS 2012. I installed with Nuget the <code>EntityFramework</code> (version 6.1.1), and add references to the <code>System.Data</code> and <code>System.Data.Entity</code>, but when I open a new class in the solution and refering to DbContext, it says:</p>
  
  <blockquote>
    <p>"The type or namespace name 'DbContext' could not be found (are you
    missing a using directive or an assembly reference?)"</p>
  </blockquote>
  
  <p>It's weird beacuse the DbContext is green, like every recognized class, when I press F12 to look into the DbContext class it brings me to the <code>System.Data.Entity.DbContext</code> class as it should be.</p>
  
  <pre><code>public DbContext MyContex { get; set; }
  </code></pre>
  
  <p>The same happanes with DbSet</p>
  
  <pre><code>public DbSet&lt;TEntity&gt; MySet { get; set; }
  </code></pre>
  
  <p>What else am I missing?</p>
