This method has better performance (twice faster) and need lower memory as it doesn't copy data to MemoryStream:

Bitmap GetBitmapFromSource(BitmapSource source) //, bool alphaTransparency
{
    //convert image pixel format:
    var bs32 = new FormatConvertedBitmap(); //inherits from BitmapSource
    bs32.BeginInit();
    bs32.Source = source;
    bs32.DestinationFormat = System.Windows.Media.PixelFormats.Bgra32;
    bs32.EndInit();
    //source = bs32;

    //now convert it to Bitmap:
    Bitmap bmp = new Bitmap(bs32.PixelWidth, bs32.PixelHeight, PixelFormat.Format32bppArgb);
    BitmapData data = bmp.LockBits(new Rectangle(Point.Empty, bmp.Size), ImageLockMode.WriteOnly, bmp.PixelFormat);
    bs32.CopyPixels(System.Windows.Int32Rect.Empty, data.Scan0, data.Height * data.Stride, data.Stride);
    bmp.UnlockBits(data);
    return bmp;
}

why do you want/need to use wpf-specific things?

look at this snippet How to convert BitmapSource to Bitmap

Bitmap BitmapFromSource(BitmapSource bitmapsource)
{
    Bitmap bitmap;
    using (MemoryStream outStream = new MemoryStream())
    {
        BitmapEncoder enc = new BmpBitmapEncoder();
        enc.Frames.Add(BitmapFrame.Create(bitmapsource));
        enc.Save(outStream);
        bitmap = new Bitmap(outStream);
    }
    return bitmap;
}

Usage:

pictureBox1.Image = BitmapFromSource(yourBitmapSource);

If you want to open an image file...:

pictureBox1.Image = System.Drawing.Image.FromFile("C:\\image.jpg");

Is it OK for you?

ImageSource imgSourceFromBitmap = Imaging.CreateBitmapSourceFromHBitmap(bitmap.GetHbitmap(), IntPtr.Zero, Int32Rect.Empty, BitmapSizeOptions.FromEmptyOptions());
