Hi !

I get this message, when I want use System.Drawing and System.Windows.Forms
latest mono,monodevelop,gtk-sharp etc.
Code:

using System;
using System.Drawing;
using System.Windows.Forms;

public class HelloWorld : Form
{
    static public void Main ()
    {
        Application.Run (new HelloWorld ());
    }

    public HelloWorld ()
    {
        Button b = new Button ();
        b.Text = "Click Me!";
        b.Click += new EventHandler (Button_Click);
        Controls.Add (b);
    }

    private void Button_Click (object sender, EventArgs e)
    {
        MessageBox.Show ("Button Clicked!");
    }
}

Re: monodevelop C# error

Try downloading the Gtk# 2.0 devel package.

Also, C# sucks.
