title: WIA 2.0 Duplex scanning
body: <p>Since Vista, Windows is shipped with WIA 2.0 (wiaaut.dll). 
  According to the following KB article and many of my findings on various forums, duplex scanning is no longer possible using WIA 2.0. Yet, the article mentions the use of native WIA 2.0, what would make duplex scanning possible.
  (<a href="https://support.microsoft.com/en-us/kb/2709992" rel="noreferrer">https://support.microsoft.com/en-us/kb/2709992</a>)</p>
  
  <p>According to the WIA 2.0 documentation (<a href="https://msdn.microsoft.com/en-us/library/windows/desktop/ms630196(v=vs.85).aspx" rel="noreferrer">https://msdn.microsoft.com/en-us/library/windows/desktop/ms630196(v=vs.85).aspx</a>), duplex scanning is possible but using the new WIA_IPS_DOCUMENT_HANDLING_SELECT (3088) property.</p>
  
  <p>My issues are:</p>
  
  <ul>
  <li>I have no idea how to use native WIA, I suspect when using C# its just not possible.</li>
  <li>I cant find a way to set the new WIA_IPS_DOCUMENT_HANDLING_SELECT property, as the property is not present in my wiaDevice properties. According to WiaDef.h, its property id is still 3088 and the only possible value is 0x400 (1024).</li>
  </ul>
  
  <p>If anyone could help me (and I think many others) out on this, it would be much appreciated!</p>
  
  <p>Greetings,</p>
