Answer 1

First, locate the directory where is the System.Drawing.dll file (for example /opt/mono-4.4.0/lib/gac/System.Drawing/4.0.0.0__b03f5f7f11d50a3a/System.Drawing.dll).

Create a file in the same directory called System.Drawing.dll.config with the following content, updating the directory to the correct location of libgdiplus.so:

<configuration>
  <dllmap dll="gdiplus.dll" target="/opt/mono-4.4.0/lib/libgdiplus.so"/>
</configuration>
