title: Use third party code in C#
body: <p>I would like to use the following code in my program  (<a href="http://sshnet.codeplex.com/" rel="nofollow">http://sshnet.codeplex.com/</a>)<a href="http://sshnet.codeplex.com/" rel="nofollow">SFTP</a></p>
  
  <p>I downloaded it and put into the same folder where my C# project is. I aslo added code:</p>
  
  <pre><code>using Renci.SshNet;
  using Renci.SshNet.Sftp;
  </code></pre>
  
  <p>Now I need to tell Visual Studio where to look for it. I tried "Add Reference", but what I downloaded contains only files with extension .cs no .dll.</p>
  
  <p>What do I do next?</p>
  
  <p>I read a couple of books about C# (By Troelsen and Michaelis), but all this assebly business is not clear to me.</p>
