Screenshot of 'Mono' application title

Consider this small testcase:

namespace GtkApplicationTest
{
	public class Program
	{
		public static int Main(string[] args)
		{
			Gtk.Application app = new Gtk.Application("org.example.GtkApplicationTest", GLib.ApplicationFlags.FlagsNone);
			app.Activated += (sender, e) => 
			{
				if (app.Windows.Length > 0)
				{
					app.Windows[0].Present();
				}
				else
				{
					Gtk.Window window = new Gtk.Window("GtkApplicationTest");
					window.Application = app;
					window.Show();
				}
			};

			return app.Run(0, null);
		}
	}
}

Expected result (unique application) is OK, is only has one issue: it shows 'Mono' as the application title (see attachment).

Gnome-shell is generating an "app name" based on the entry executable (which is Mono, since it's loading your managed exe).

See http://stackoverflow.com/questions/9324163/how-to-set-application-title-in-gnome-shell

You could also try renaming your executable. There are two ways to do this:

Pass the -a argument to exec in your launch script:

exec -a "MyAppName" mono myapp.exe

and by p/invoke prctl - see MD's unixSetProcessName:

https://github.com/mono/monodevelop/blob/master/main/src/core/MonoDevelop.Core/MonoDevelop.Core/Runtime.cs#L297

You probably should do both, they each affect different things, and I'm not sure which will affect gnome-shell.

Ah thanks for your comprehensive solution, I've tried googling that but didn't find it. Sorry for incorrectly filing a bug!
