title: Where can I find "microsoft.office.interop.excel" in the Assembly / COM browser window?
body: <p>I wanted to add the reference <code>microsoft.office.interop.excel</code> to my project. </p>
  
  <p>I went to Project > Properties > References > and clicked the <code>Add...</code> button.</p>
  
  <p>In the <code>Reference Manager</code> dialog, I have the following options:</p>
  
  <ul>
  <li>Assemblies</li>
  <li>Frameworks</li>
  <li>Project folder</li>
  <li>COM</li>
  <li>Search</li>
  </ul>
  
  <p>There is a search window. I typed <code>microsoft.office.interop.excel</code>, but it is just not found.</p>
  
  <p>I had to browse for it to locate it manually on my drive.</p>
  
  <p>Why? </p>
