I believe you have to use interop (source):

using System.Windows.Interop;
using System.Windows.Media.Imaging;

public static ImageSource AsImageSource(
    this Image image) where TColor : IColor, new()
{
    return Imaging.CreateBitmapSourceFromHBitmap(image.Bitmap.GetHbitmap(),
                       IntPtr.Zero, Int32Rect.Empty,
                       BitmapSizeOptions.FromEmptyOptions());
}

Which could be used like this:

void timer_Elapsed(object sender, ElapsedEventArgs e)
{
        using (Image frame = capture.QueryFrame())
        {
                if (frame != null)
                {
                        var bmp = frame.AsImageSource();
                }
        }
}

If the interop doesn't perform well enough, take a look at the source of Image.ToBitmap and Image.get_Bitmap to see how you could implement your own WriteableBitmap.
