Vista - OperationContract formatting problem

HI,

I'm working with winfx Beta2 and having a problem controlling the way
OperationContract methods are serialized/deserialized.

I need a pretty high granularity controll similar to the one given in asmx
web methods using [SoapDocumentMethodAttribute] [XmlElement] and friends.
(e.g. attributed controll over the method paramters elements names, name of
return value, name of result element, etc).
--------------------------------------------------------------------------------
example:

[ServiceContract]
interface MyService
{
[OperationContract]
MyObject DoSomething ( MyObject obj );
}

Indigo Default Request Serialization:

<s:Envelope>...
<s:Body>
<DoSomething>
<obj>....object serialization..<obj>
</DoSomething>
</s:Body>
</s:Envelope>

Desireable Request Serialization:

<s:Envelope>...
<s:Body>
<DoSomething>
<MyObject>....object serialization..<MyObject>
</DoSomething>
</s:Body>
</s:Envelope>

Indigo Default Response Serialization:

<s:Envelope>...
<s:Body>
<DoSomethingResponse>
<DoSomethingResult>...object serialization..</DoSomethingResult>
</DoSomethingResponse>
</s:Body>
</s:Envelope>

Desirable Response Serialization:

<s:Envelope>...
<s:Body>
<DoSomethingResult>
<MyObject>...object serialization..</MyObject>
</DoSomethingResult>
</s:Body>
</s:Envelope>

Any suggestions?

Thanks.

Use the XmlSerializerFormatAttribute to decorate your OperationContract

[ServiceContract]
interface MyService
{
[OperationContract]
[XmlSerializerFormat]
MyObjectResponse DoSomething ( MyObjectRequest obj );
}

and IXmlSerializable interface for your custom serialization/deserialization
Request/Response object, see the following code snippet:

public class MyObjectRequest : IXmlSerializable
{
// fields
private MyObject _myObject;

// properties
public MyObject MyObject { get; set;}

// constructors
public MyObjectRequest() {}

// IXmlSerializable Members
public System.Xml.Schema.XmlSchema GetSchema()
{
// create schema
return null;
}
public void ReadXml(XmlReader reader)
{
reader.ReadStartElement("DoSomething", "MyNamespace");
while (reader.NodeType != XmlNodeType.EndElement)
{
MyObject = reader.ReadElementContentAsObject("MyObject",
"MyNamespace") as MyObject;
// more objects
reader.MoveToContent();
}
}
public void WriteXml(XmlWriter writer)
{
writer.WriteStartElement("DoSomething", "MyNamespace");
if (MyObject != null)
{
XmlSerializer xs = new XmlSerializer(MyObject.GetType());
xs.Serialize(writer, MyObject);
}
// more objects
writer.WriteEndElement();
}
}
