WCF, containers in DataContract

Question

Hi I need to pass some container of objects to WCF call

[DataContract]
class Foo
{
 // other fields omited

 [DataMember]
 public List<Foo> MyList;
}

Is it OK for serialization? If not what are my options?

Answer 1

It's ok but the resulting type will be an array and not a list. I'm partial to using array in the contract just to make sure I don't try to use it as list someplace else.
