It appears you have asked this question on MSDN and I answered you there.

I suggested that your issue may not be with QR barcode generation, but rather with combining 2 images so that the smaller logo image does not affect the readability of the barcode.

Since QR barcode is fairly robust, you can use a simple code to combine the images directly:
using (Graphics g = Graphics.FromImage(bmp))

g.DrawImage(smaller_image, (bmp.Width - smaller_image.Width), (bmp.Height - smaller_image.Height));

If you want one library to handle both barcode creation and bitmap insertion, you could use the LEADTOOLS Barcode Pro library:
