title: What is Uri Pack, and ":,,," in a BitmapImage?
body: <p>What I add a Image.Source I have to type the following:</p>
  
  <pre><code>playIcon.Source = new BitmapImage(new Uri(@"pack://application:,,,/TempApplication2;component/Images/play.png"));
  </code></pre>
  
  <p>I'm moving from web development to WPF C# and I don't get why setting a Path has extra stuff in it, where in CSS I simply add a Path string.</p>
  
  <p>Can someone explain why there is Uri, pack, and the ":,,,", Application2:component? </p>
  
  <p>I'm new to WPF C#.</p>
