Where do i find System.Windows.Media ? The Media is not exist
<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>
