title: Upgrade to EF 6.1.1 makes effect of [NotMapped] disappear
body: <p>I have upgraded from EF 4.3.1 to 6.1.1 and now it seems like the annotation [NotMapped] is useless. Yes, i have change to correct assembly and everything looks fine on compilation.</p>
  
  <p>Everywhere where [NotMapped] is present the property is handled as a domain property and i get an error that EF can't find the matching column in database.</p>
  
  <p>Example:</p>
  
  <pre><code>private bool _authenticated = true;
  
          [NotMapped]
          public bool Authenticated
          {
              get { return _authenticated; }
              set { _authenticated = value; }
          }
  </code></pre>
  
  <p>Yes, it seems like i can work around this by adding...</p>
  
  <pre><code> modelBuilder.Entity&lt;User&gt;().Ignore(x =&gt; x.Authenticated);
  </code></pre>
  
  <p>...but then, whats the use of [NotMapped] in EF6? </p>
  
  <p>(Worked perfect before upgrade)</p>
