[Mono-list] using DataContractSerializer on Objects with read only fields

[ptr2009]

hey all

  I am attaching a small sample illustrating my problem. I have a simple
Object that has few readonly
fields with DataMember. 

Under mono 2.4.2.3 I get the following exception ?

Unhandled Exception:
System.Runtime.Serialization.InvalidDataContractException: DataMember field
System.String name must not be read-only.


The Program runs without errors under .NET 3.5. Is this a known issue ?

Thanks
Raj
