Unhandled exception. System.TypeInitializationException: The type initializer for 'Gtk.Application' threw an exception.
 ---> System.DllNotFoundException: Gtk: libgtk-3-0.dll, libgtk-3.so.0, libgtk-3.0.dylib, gtk-3.dll
   at GLibrary.Load(Library library)
   at Gtk.Application..cctor()

   at Gtk.Application.Init()
   at GtkSharp_Application2.Program.Main(String[] args) in I:\Проекты\Programs\GtkSharp Application2\GtkSharp Application2\Program.cs:line 9

I using WSL, but i think problem not caused by this.

I expecting run application by Linux, but that don't working.

Solution

  • I fixed that by installing gtk package sudo apt install libgtk-3-0
