Update example OnnxObjectDetectionWeb from ML.NET 1.4.0 to 2.0.0 getting error?

I changed the packages from 1.4.0 to 2.0.0 and got this error, apparently version 2.0.0 no longer has the Drawing.Common package, so I had to install it myself. I got an error

Not sure but one common fix is to use MLImage instead of Bitmap.
