title: WindowsDriver.common.targets error
body: <p>I have installed Visual Studio 2013 then installed Windows Driver Kit (WDK) 8.1. I'm using Windows 7. I already had a project which is a modified fastfat. I was building that using VS 2012 and everything was fine. But today when I try to build the same project using VS2013 I get the following error:</p>
  
  <p>C:\Program Files (x86)\Windows Kits\8.1\build\WindowsDriver.common.targets(77,5): error : Unknown or unsupported property value (Vista) for TargetVersion</p>
  
  <p>Note that I ran the clean procedure before doing the build.</p>
  
  <p>Does anyone know what to try next?</p>
