Cannot find the System.Windows.Forms assembly

I am trying to build a WinForms application, and I'm using the Visual
Studio C# 2005 Express edition. Doesn't it bind to .NET 2.0 by
default, and shouldn't it be able to find the dll without any settings
being tweaked ? I'm sure the answer is simple, but I couldn't find
anything after a brief trawl of the net.

What do you mean bind to .Net 2.0? Visual Studio 2005 (in any flavor or
version) does use the .Net 2.0 framework. I don't understand what you mean
when you say "find the dll". The .Net framework is made up of lots of
dll's. Can you be more specific as to what you are trying to do that is not
working?

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!

You need to add a reference to the system.windows.forms.dll to your project.

This is done automatically if you create a windows application project,
so you have to have created a different kind of project.
