title: Adding Microsoft.DirectX.DirectInput To Visual Studio 2013 Express for Windows Desktop
body: <p>I am trying to use some classes from the <code>Microsoft.DirectX.DirectInput</code> namespace, in the past if there was a namespace I couldn't use in my project I would just go to references and add the file with that name to my project, except that I cannot find the file in the list.</p>
  
  <p>How can I use this namespace?</p>
