Linux App Service - 'System.Drawing.GDIPlus' threw an exception. Unable to load shared library 'gdiplus' or one of its dependencies

Question

Hello,

i´m trying to use System.Drawing in a linux web app, but i´m getting the exception below.

System.TypeInitializationException: The type initializer for 'System.Drawing.GDIPlus' threw an exception.

System.DllNotFoundException: Unable to load shared library 'gdiplus' or one of its dependencies. In order to help diagnose loading problems, consider setting the LD_DEBUG environment variable: libgdiplus: cannot open shared object file: No such file or directory

I tried to execute the following commands in ssh shell, but still not working.

• apt-get update
• apt-get install -y --allow-unauthenticated libx11-dev
• apt-get install -y --allow-unauthenticated libc6-dev
• apt-get install -y --allow-unauthenticated libgdiplus

Running on Windows its working fine.

@Marcos Vinicius dos Santos , Apologies for the delay and any inconvenience with this! I completely understand this issue could be frustrating.

If you haven't tried this already, kindly add the code in Stack setting >> as Startup command "apt-get update && apt-get install -y apt-utils libgdiplus libc6-dev && dotnet yourwebappname.dll"

You may checkout this document for more details on adding a startup script for Linux WebApp.

If the issue still persist, to isolate, could you please check if this works locally in a Linux docker container and code issue (for cross platform version). Please check the approach outlined in this blog and see if it helps.
