title: Make MSDeploy (Visual Studio) not delete App_Data folder but delete everything else
body: <p>I'm using Visual Studio's <code>Publish</code> button to deploy my website, and want a different App_Data folder on the server. There's a checkbox for <code>Leave extra files on destination (do not delete)</code> which prevents my App_Data folder from getting deleted, but then it'll eventually accumulate a lot of vestigial files as the website changes.</p>
  
  <p>Is there any way to make it exclude just App_Data when it deletes everything?</p>
