title: Has the generic version of HttpResponseMessage been removed from the ASP.NET WebApi?
body: <p>I just finished installing VS 2012 RC and have started working with the ASP.NET Web API. I am basing my work on some tutorials from PluralSight which I've been using as reference.</p>
  
  <p>In every tutorial and article which I've used, I notice that they are using a generic version of <code>HttpResponseMessage</code> in the return type of <code>Action</code>, but to my surprise this object was not available to me while coding. I thought perhaps the issue was just an incorrect namespace reference, but that does not seem to be the case.</p>
  
  <p>Can anyone point me toward some source code or reference material on how to utilize the generic <code>HttpResponseMessage</code> object that PluralSight uses in their videos?</p>
