title: How can I automatically add existing items to a Visual Studio project?
body: <p>I have a tool which <strong>dynamically</strong> <strong>generates</strong> .xaml and .xaml.cs files and puts them in the appropriate Visual Studio <strong>directory</strong>. </p>
  
  <p>To <strong>add</strong> them to the project, I have to then:</p>
  
  <ul>
  <li>right-click on that directory</li>
  <li>choose "add existing item"</li>
  <li>navigate to the matching directory on the hard drive</li>
  <li>select the two files that were created</li>
  <li>click ok</li>
  </ul>
  
  <p><strong>Is there a way for me to tell the project to "include all existing items under the project folder on the hard drive"?</strong></p>
