JSON Serialization in WCF - Are Object Properties Ordered Alphabetically?

Question

I created a WCF REST service that returns JSON, but the properties in serialized objects are returned in alphabetical order.

Is it possible to change this?

Try setting the order property on your data elements for your data contracts:

[DataContract]
public class MyClass
{
     [DataMember(IsRequired = true, Order = 1)]
     public int Id { get; set; }
}
