title: How to find or use a custom library from the GAC
body: <p>I'm using Windows 8 and I'm trying some things with the Global Assembly Cache (GAC). I created a simple library called AAA, I added a sn key for this in my VisualStudio project, and built it. Later <code>gacutil -i AAA.dll</code> was run. The result message was that the library is successfully installed in the GAC.</p>
  
  <p>I'm also able to do: <code>gacutil -l AAA</code>, it returns some information about the library.</p>
  
  <p><strong>But I'm wondering:</strong> </p>
  
  <ol>
  <li><p>How to find the GAC instance file or any GAC reference for my AAA library. I looked in <code>C:\Windows\Assembly</code>, but I was not able to find the file.</p></li>
  <li><p>How to use GAC library? I was not able to find AAA dll in the Add-Reference window in Visual Studio, why?</p></li>
  </ol>
