title: Markdown wikiengine
body: <p>Do anyone know of a wiki engine that uses markdown?</p>
  
  <p>I'm not going to use ASP.Net, but do post ASP.Net based solutions anyway if you know any.</p>
  
  <h2>Update</h2>
  
  <p>Please note the <strong>.Net</strong> tag. I'm only interested in Markdown engines that have been built using .Net.</p>
