Wondering if anyone else has run into this. I'm programming a codeunit to print PDF's and when I go to the Assembly List I'm only showing System.Diagnostics.Contracts, Debug, Tools, and Tracing. I'm missing ProcessStartInfo, ProcessWindowStyle, and Process. I checked and .net 3.5 and 4.6 are installed. I even tried reinstalling and still nothing. Anyone have any ideas of what I'm missing? I spent 2 hours on Google and haven't found anything.
