MbUnit Cannot get DataFixture test to run

[GatoRat]

I cannot get DataFixture tests to run. I even created a small test
(dll) assembly using your sample code with the same xml file. I am
using 2.3.7 and TestDriven 1256d. I am using .NET 2.0 and Visual Studio
2005 release. A standard test worked fine. My .cs test file is:

using System;
using System.Text;
using MbUnit.Framework;
using System.Xml;

namespace MbUnitTest
{
        [DataFixture]
        [XmlDataProvider("C:/sample.xml", "DataFixture/Customers")]
        public class DataDrivenTests
        {
                [ForEachTest("/User")]
                public void ForEachTest(XmlNode node)
                {
                        Assert.IsNotNull(node);
                        Assert.AreEqual("User", node.Name);
                        Console.WriteLine(node.OuterXml);
                }
        }
}

My XML file is:

<DataFixture>
  <Employees>
    <User Name="Mickey" LastName="Mouse" />
  </Employees>
  <Customers>
    <User Name="Jonathan" LastName="de Halleux" />
    <User Name="Voldo" LastName="Unkown" />
  </Customers>
</DataFixture>
