What is the command line you used to compile the application?

Did you reference the System.Windows.Forms assembly when you compiled? 

The command line option :  -reference:ASS     References the specified
assembly (-r:ASS)

Subject: [Mono-list] namespace System.Windows.Forms cannot be found


This might be a real beginners-question, but I couldn't find an answer
anywhere on the internet, nor in the gnome documentation / Windows Forms
home page.

Issue is that I try to compile a very simple hello-world winforms
application (Linux, Fedora FC3). I installed mono 1.1.6 + winforms rpm + all
required dependencies (libgdiplus, cairo, etc), and I see a
System.Windows.Forms directory in '/usr/lib/mono/gac/'.

After invoking mcs I get the following error:

hello.cs(2) error CS0234: The type or namespace name `Windows' could not be
found innamespace `System'

Could someone please help me out?

Many thanks,

Danny Brugman

BTW Here is the source:

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

class MyForm : Form
   MyForm ()
     Text = "My First MWF App";

   protected override void OnPaint (PaintEventArgs e)
     e.Graphics.DrawString ("Hello world", Font,
         new SolidBrush (Color.Black), ClientRectangle);

   static void Main ()
     Application.Run (new MyForm ());
