title: Using opencv for eye movement detection for windows store apps in c#
body: <p>I'm trying to track the movement of eyes using opencv for a windows store app i'm making in <code>c#</code>.</p>
  
  <p>i have the live feed from the camera using <code>MediaCapture</code>.</p>
  
  <p>i've been looking this up online for so long and i see people referring to <a href="https://github.com/MSOpenTech/opencv" rel="nofollow">MSOpenTech/opencv</a> here but i can't follow the instructions because the readme file is outdated.</p>
  
  <p>i also cloned the repository to try and run the sample code and when I run the winrt_universal phoneTutorial I keep getting the erorr : </p>

    Visual Studio tools by selecting the Project menu or right-click the

  <p>i don't know what i'm doing wrong with the sample and i'm not sure how to go about following the instructions for the opencv.</p>
  
  <p>thank you!</p>
