Passing data from client to wcf service to domain layer

I want a consumer app to send some data structure to a wcf service, then this service pass the data to the business model objects.

What I would like is to avoid the need to copy manually each property of the service data object to a new business object.

For example:

[DataContract]
public class MyServiceData
{
    [DataMember]
    public Property1() { get; set;}
    [DataMember]
    public Property2() { get; set;}
    [DataMember]
    public Property3() { get; set;}
}

public class MyWcfService : IMyWcfService 
{
    public void Operation1(MyServiceData data)
    {
        var obj = new DomainObject();
        obj.Property1 = data.Property1;
        obj.Property2 = data.Property2;
        obj.Property3 = data.Property3;

        obj.DoSomething();
    }
}

I could put MyServiceData class in the business object layer, but I don't think it is a good thing to use these wcf service attributes in a business model object.

Is there any design pattern I could use to achieve this ?
