title: Memory leak in image control wpf
body: <p>I am working with Aforge.Net to get a single frame from webcam and display it through image control. whenever a user clicks the button i am trying to update the image control with a new image, fetched from the webcam . Everything seems to work fine but the memory usage keeps on going up. I don't no how to fix this issue in my app.</p>
  
  <pre><code>Bitmap _image = aforge.Test();
  WebCamVideo.Source = System.Windows.Interop.Imaging.CreateBitmapSourceFromHBitmap(
     _image.GetHbitmap()
    , IntPtr.Zero
    , System.Windows.Int32Rect.Empty
    , BitmapSizeOptions.FromWidthAndHeight(
          _image.Width
        , _image.Height)
  );
  WebCamVideo.Source.Freeze();
  _image.Dispose();
  </code></pre>
