title: Trying to add reference to project in Visual Studio 2012, "no items found"
body: <p>I'm trying to add a reference to <code>System.dll</code> and <code>System.drawing.dll</code> to my project in Visual Studio 2012. I'm doing this by right clicking the project, clicking "references", and then clicking "Add new reference".</p>
  
  <p>It seems like the following screen should have a lot of options, but for me it simply says "No Items Found". In the screen it says my targeted framework is <code>.NETFramework, Version=v4.0</code>.</p>
  
  <p>Is there anything else I need to be doing in order to make the options show up?</p>
