title: Where do i find System.Windows.Media ? The Media is not exist
body: <p>I tried:</p>
  
  <pre><code>using System;
  using System.Collections.Generic;
  using System.ComponentModel;
  using System.Drawing;
  using System.Data;
  using System.Text;
  using System.Windows.Forms;
  using AviFile;
  using ScreenShotDemo;
  using System.Threading;
  using System.Windows.
  </code></pre>
  
  <p>In my new class but in the bottom system.Windows.
  There is no Media</p>
  
  <p>Im using visual c# pro 2012 and .net 4.5
  Tried to add it as reference looked for it in .net and in COM but it's not there.</p>
  
  <p>The reason i need it is that in my code i have PixelFormat and it's not exist:</p>
  
  <pre><code>Bitmap bmpScreenShot = new Bitmap(currentScreen.Bounds.Width,
  currentScreen.Bounds.Height,
  PixelFormat.Format32bppArgb);
  </code></pre>
  
  <p>PixelFormat not exist.</p>
