Sorry, I wasn't clear enough. This is the code I'm trying to compile:
using System;
using System.Windows.Forms;

namespace WinFormsTest
{
   class SimpleHelloWord: Form
   {
       [STAThread]
       public static int Main(string[] args)
       {
           Application.Run(new SimpleHelloWord());
           return 0;
       }

       public SimpleHelloWord()
       {
           this.Text = "Hello World";
       }
   }
}

Compilation fails at the second line .. "The type or namespace name
'Windows' does not exist in the namespace 'System' (are you missing an
assembly reference?)". I assume this is because it cannot find the
System.Windows.Forms dll. However if this ships with .NET 2.0 by
default, and VS C# 2005 Express Edition uses the 2.0 framework, where
am I going wrong ? Been scratching my head!
