问题
I've been dealing with deploying an API that uses System.Drawing for a few weeks. I had it running in an Azure App Service and I used to get a "GDI+ generic exception". Now, out of nowhere started working. I looked for Microsoft announcements but couldn't find anything.
回答1:
GDI+ is still not supported now, please refer to here.
