title: Assembly installed into the GAC not showing up in Visual Studio
body: <p>This sounds related to <a href="https://stackoverflow.com/questions/1934894/visual-studio-2010-cannot-add-assembly-references-from-the-gac">this question</a>, but they aren't the same thing.  That question had <em>no</em> assemblies showing up.  Mine has everything except the specific one I installed.</p>
  
  <p>I'm hoping someone has a solution to this... am I doing something wrong?  Or did I find some bug in VS?</p>
  
  <p>I am using Visual Studio 2010 Professional Beta 2 on Windows 7 Ultimate.  I just downloaded Rhino Mocks and decided to install it into the GAC using the command-line utility GACUTIL.  I then rebooted.</p>
  
  <p>Here you can see the assembly in my GAC (click to enlarge):</p>

  <p>And here is the list of assemblies available to me in Visual Studio:</p>

  <p>Here is the command prompt where I installed it, and then confirmed it:</p>
