title: system collections specialized not found
body: <p>Trying to compile a c++/cli program using VS 2008 and .NET framework 3.5</p>
  
  <p>These statements work:</p>
  
  <pre><code>using namespace System::Collections;
  using namespace System::Collections::Generic;
  </code></pre>
  
  <p>but the specialized collection namespace doesn't show up</p>
  
  <pre><code>using namespace System::Collections::Specialized;
  </code></pre>
  
  <p>What am I doing wrong? Is there some assembly I am missing?</p>
