You can control the way WCF serialize objects. Take a look here here

Set the IsRequired and EmitDefaultValue properties of the DataContract attribute to false:

[DataMember(IsRequired = false, EmitDefaultValue = false)]
public string Name { get; set; }

[DataMember(IsRequired = false, EmitDefaultValue = false)]
public byte? Age { get; set; }
