TypeBuilder with DataContract and DataMembers

I'm generating a dynamic type on the fly with a DataContract attribute and DataMembers. I've verified the type is getting generated correctly with DataContract and DataMember attributes using reflection on the generated type.开发者_运维技巧

I then generate a ServiceContract type on the fly that includes operation with said types.

However, when I add a ServiceReference from the client, my DataContract types get generated with the client with no properties/DataMembers.

Any idea what's going wrong here?

Thanks.

My TypeBuilder properties' methods were marked with MethodAttributes.Virtual.

Another great well documented feature of the DataContractSerializer.
