title: Microsoft.Practices.Unity nowhere to be found
body: <p>Using Visual Studio 2012 and have no idea why <code>Microsoft.Practices.Unity</code> is not under the assembly tab (or any tab for that matter) when I try to add it as a reference.  Working on a C# solution that was originally a Visual Studio 2010 solution on Visual Studio 2012.</p>
  
  <p>Is this namespace deprecated and/or is there another namespace where I can use the <code>InjectionConstructor</code> object?</p>
  
  <p>Anyone have any idea why my Microsoft VS 2012 does not have a <code>Microsoft.Practices.Unity</code> namespace?</p>
