I’ve been trying all day to get GTK# working in Visual Studio 2010 on Windows Server 2008 R2 x64 so that I can start writing nice cross-platform GUI applications, but I’m somewhat new to C# and I’m having a world of trouble.
I installed the latest Mono for Windows which includes GTK#. I also installed a Mono 2.10.8 profile to be the target framework of my project loosely following the guide from here: http://erictummers.wordpress.com/2012/01/25/target-mono-from-visual-studio/
I created a new Windows Forms application and removed references to the windows forms stuff and adding references for GTK# stuff, loosely following the guide from here: http://jrwren.wrenfam.com/blog/2008/11/01/gtk-in-visual-studio-2008-on-vista-x64/
I also added a reference to gtk-dotnet in addition to the ones from that guide.
This is my application’s complete code:
using System;
using System.Runtime.InteropServices;
using System.Collections.Generic;
using System.Linq;
using Gtk;
namespace GridToGo
{
static class Program
{
[STAThread]
static void Main()
{
Application.Init();
Window myWin = new Window("My first GTK# Application! ");
myWin.Resize(200, 200);
myWin.Destroyed += new EventHandler(myWin_Destroyed);
Label myLabel = new Label();
myLabel.Text = "Hello World!!!!";
myWin.Add(myLabel);
myWin.ShowAll();
Application.Run();
}
static void myWin_Destroyed(object sender, EventArgs e)
{
Application.Quit();
}
}
}
When I try to run this with any configuration, I get the following exception:
System.TypeInitializationException was unhandled
Message=The type initializer for 'Gtk.Application' threw an exception.

I can’t figure out how to get it to find that dll! I even tried copying 4 copies of the DLL into pretty much every folder in the solution with the following names: glibsharpglue-2 glibsharpglue-2.dll glibsharpglue-2.o glibsharpglue-2.o.dll! I also even tried installing the GTK all-in-one package from the GTK site and adding its bin folder to my system path, and then copying the same 4 dlls into that folder, all with no luck.
Any advice for my crazy problem? I feel like I’m missing something big here. >_<
I figured it out! Mono for Windows was completely unnecessary. GTK# for .NET is what I needed. For anyone in the future wanting to set up their Windows environment for cross platform GTK# development, here are the steps I followed:
