Serializing works but deserializing is missing data.

Question

I am exposing a POST method in a wcf service for a given set of nested classes. Everything works fine, even serializing, except when I post the *same* xml I create through serializing an instance, the Umber.Amethysts property is empty.
[XmlRoot("MyRoot", Namespace = "myNamespace")]
public class MyRoot
private Indigo indigo;
public MyRoot()
this.indigo = new Indigo();
[XmlElement("Indigo")]
public Indigo Indigo
get
return this.indigo;
set
this.indigo = value;
public class Indigo
private Maroon maroon;
private Umber umber;
public Indigo()
this.maroon = new Maroon();
this.umber = new Umber();
[XmlElement("Maroon")]
public Maroon Maroon
get
return this.maroon;
set
this.maroon = value;
[XmlElement("Umber")]
public Umber Umber
get
return this.umber;
set
this.umber = value;
public class Umber
private List<Amethyst> amethysts;
public Umber()
this.amethysts = new List<Amethyst>();
[XmlElement("Amethysts", Namespace = "")]
public List<Amethyst> Amethysts
get
return this.amethysts;
set
this.amethysts = value;
public class Amethyst
private string name;
private string value;
[XmlElement("Name")]
public string Name
get
return this.name;
set
this.name = value;
[XmlElement("Value")]
public string Value
get
return this.value;
set
this.value = value;
If I manually create the instance:
MyRoot data = new MyRoot
Indigo = new Indigo
Maroon = new Maroon
SomeField = "text..."
Umber = new Umber
Amethysts = new List<Amethyst>
new Amethyst { Name = "foo", Value = "bar"},
new Amethyst { Name = "baz", Value = "biz"}
It serializes a pair of <Amethyst> tags but posting this very same serialized text representation back leaves the Umber element empty?
Anyone know what I am missing?
Thanks!

Hi Ritmo2k,
I have tested your code in my side, then in oder to get the xml data, I have created the following OperationContract GetDataUsingDataContract() with the RequestFormat=WebMessageFormat.Xml
and ResponseFormat=WebMessageFormat.Xml:
public MyRoot GetDataUsingDataContract()
MyRoot data = new MyRoot
Indigo = new Indigo
Maroon = new Maroon
SomeField = "text..."
Umber = new Umber
Amethysts = new List<Amethyst>
new Amethyst { Name = "foo", Value = "bar"},
new Amethyst { Name = "baz", Value = "biz"}
return data;
After that I can get the following result as following:
So please try to rebuild your project and test it again.
If it still can not help, please try to post a simple reproduce project in here.
Besides, if I have misunderstood you, please feel free to let me know.
Best Regards,
