Edited Issue: Can't update entity by WCF Data Service Client when it has readonly property [531]

For example, define model:

public class Car
{
public int ID { get; set;}
public int WheelCount {
get {
return 4;
}
}
}

Build edm model:
ODataConventionModelBuilder builder = new ODataConventionModelBuilder();
builder.EntitySet<Car>("Cars");
return builder.GetEdmModel();

Generate client code by ASR, and write following code to post a new car:
Container c = new Container(new Uri("http://localhost:50232/"));
c.AddObject("Cars", new Car());
c.SaveChanges();

Server side reports following exceptions:

System.ArgumentException occurred

Message=Property set method not found.
