[Mono-list] DataContractSerializer differs from .Net on Generic class

[Cocai]

Hi Atsushi,

After some other test I have discovered:
 MyGenerics<string> in .Net become i:type=\"b:SpeakerOfstring\" but in Mono
is i:type=\"d3p1:SpeakerOfString\" (note how is written OfString)

I have tried with [DataContract(Name = "MyGenericsOf{0}")] that in .Net
eliminate the random suffix, but in Mono I received this exception by
DataContractSerializer: "System.Argument Exception: localName must be a
valid NCName."; the problem is with "{0}".
Also, If I define the derived class  
pubblic class NewMyGenerics : MyGenerics<MyClass>

and adding [KnownType(typeof(NewMyGenerics))] to MyGenerics like this

[DataContract(Name = "MyGenerics")]
[KnownType(typeof(NewMyGenerics))]
public class MyGenerics<T>

DataContractSerializer throw "System.InvalidOperationException: There is
already a registered type for XML name
http://schemas.datacontract.org/2004/07/MyNamespace:MyGenerics"
with stack trace:
