WCF Dictionary implementing IXmlSerializable

Question

I have some WCF services which employes default DataContractSerialization. Some of the service methods return Dictionary objects. One of the clients are generating XSD files from WCF services (biztalk related) and he is requesting to convert all dictionary types to a new dictionary type which implements IXmlSerializable. I wonder, if there will be any unexpected results of this conversion which may affect the DataContract serialization somehow?

Update: Server and client share the same domain dlls, clients do not generate them from service. Maybe in the question I was missing the main point; I wonder if an object is to be serizalized through datacontract serialization, implementing IXmlSerializable in the object will cause any problems.

Answer 1

There is an unexpected problem; since domain objects are already implementing data contract serialization, there is no way to implement IXmlSerializable without modifying the whole serialization mechanism.
