runtime: System.Drawing on CentOS: Unable to load DLL 'libdl'

Any code which uses System.Drawing fails on CentOS 7.4 with the following exception:

Unhandled Exception: System.TypeInitializationException: The type initializer for 'Gdip' threw an exception. ---> System.DllNotFoundException: Unable to load DLL 'libdl': The specified module or one of its dependencies could not be found.
 (Exception from HRESULT: 0x8007007E)
   at Interop.Libdl.dlopen(String fileName, Int32 flag)
   at System.Drawing.SafeNativeMethods.Gdip.LoadNativeLibrary()
   at System.Drawing.SafeNativeMethods.Gdip..cctor()
   --- End of inner exception stack trace ---
   at System.Drawing.SafeNativeMethods.Gdip.GdipCreateBitmapFromFile(String filename, IntPtr& bitmap)
   at System.Drawing.Bitmap..ctor(String filename, Boolean useIcm)
   at gdiplus.Program.Main(String[] args) in /root/gdiplus/Program.cs:line 12

This is because by default libdl.so doesn’t exist on CentOS whereas libdl.so.2 does exist.

As a workaround you can symlink /lib64/libdl.so.2 to /lib64/libdl.so.

ln -s /lib64/libdl.so.2 /lib64/libdl.so

Program.cs:

using System;
using System.Drawing;

namespace gdiplus
{
    class Program
    {
        static void Main(string[] args)
        {
            Console.WriteLine("Hello World!");

            var bitmap = new Bitmap("test.bmp");
        }
    }
}
