XAML loading error using contentProperty - wpf

Question

I am reading up more on XAML and I have created an XML file and want to load it. It all works but when I use the ContentProperty attribute and more importantly I remove the Company.Employees tags from the XML file, I get the error "cannot add to Company" when loading the xml file.
The code is :
<?xml version="1.0" encoding="utf-8" ?>
<Company Name="BBC" xmlns="clr-namespace:XamlLoading;assembly=XamlLoading">
<Company.Owner>
<Person Name="John" Age="49"/>
</Company.Owner>
<!--<Company.Employees>
<Person Name="Dave" Age="66" />
<Person Name="Paul" Age="45"/>
</Company.Employees>-->
<Person Name="Dave" Age="66" />
<Person Name="Paul" Age="45"/>
</Company>
[ContentProperty("Employees")]
public class Company
{
public Company()
{
Employees = new List<Person>();
}
public Person Owner { get; set; }
public string Name { get; set; }
public List<Person> Employees { get; set; }
}
static void Main(string[] args)
{
using (FileStream fs = File.OpenRead(#"..\..\company.xml"))
{
Company c = (Company)XamlReader.Load(fs); * ERROR HERE
Console.WriteLine(c.Name);
Console.WriteLine(c.Owner);
foreach (var item in c.Employees)
{
Console.WriteLine("{0} : ", item);
}
Console.ReadLine();
}
}

I would suggest that you update to the latest version of .NET. Your code works great for me.
This is a very interesting case study for XAML. I have never seen it used this way before. Typically XAML is used like HTML markup for declaratively defining a user interface. Blend is a WYSIWYG editor for creating user interfaces by generating XAML.
You have demonstrated some interesting potential for realizing data from xml using the XamlReader.
