I'm just coming up to speed on .NET development, so take what I say with a grain of salt.  And please let me know if I've made an error, or if you've got better suggestions.

<<TableOfContents>>

== Install Visual Studio ==
Express is the free, single-language edition.  I installed the C# version.
http://msdn2.microsoft.com/en-us/express/

== Install NUnit ==
For creating unit tests for .NET code:
http://nunit.com/ (not nunit.org, which lags behind)
=== Create NUnit shortcut within Visual Studio ===
In Visual Studio, under {{{Tools -> External Tools...}}} add:
{{{
Title:              NUnit
Command:            C:\Program Files\NUnit 2.4.4\bin\nunit.exe
Arguments:
Initial Directory:
}}}
 Initially, I had {{{
Arguments:          $(TargetPath)
Initial Directory:  $(TargetDir)
}}}
 due to some instructions, somewhere (which I can't find at the moment.  When I did that and launched NUnit within Visual Studio (under {{{Tools -> NUnit}}}), I got an error: {{{
System.IO.FileNotFoundException : Could not load file or assembly 'nunit.framework, Version=2.4.4.0, Culture-neutral, PublicKeyToken=96d09a1eb7frra77' or one of its dependencies.  The system cannot find the file specified.
}}}
 Leaving these blank seems to work.  ''Thanks, Don.''

== Create a new project ==
If you don't know what type of project, choose "Class Library."

Create your first NUnit test fixture.  Mine is !SimpleTests.cs
{{{
using System;
using System.Collections.Generic;
using System.Text;
using NUnit.Framework;

namespace NUnitDemo
{

    [TestFixture]
    public class SimpleTests
    {
        [Test]
        public void TestNada()
        {
        }
    }
}
}}}
I don't know where the {{{using System}}} stuff came from.  I suppose that's boilerplate from {{{Project | Add Class}}}.

Add the dependencies, in this case NUnit:  Under {{{Project | Add Reference...}}} choose {{{nunit.framework}}} and press OK.

Run {{{Build | Build Solution (F6)}}}.

== Run the tests ==
Fire up the NUnit GUI.  Run {{{File | Open Project}}} and traverse to where your project lives.  If you haven't saved it, it's probably under your windows home directory in {{{Local Settings\Application Data\Temporary Projects}}}.  Within the project, look in the {{{bin\release}}} directory for the dll named after the project.

Click the 'Run' button.  Green bar?
