A custom property in a partial class does not exist AFTER it is sent to the client using WCF data services

So, I have an Event class that is generated from the Enitity Framework, I extended what it generated in partial, for example:

public partial class Event { [DataMemberAttribute()] public EventDate CurrentEventDate { get; set; } }

When I use the ON THE SERVER custom property, this is good, for example:

  [WebGet] public IQueryable<Event> EventsOn(string date) { var to Return = // Get my events here toReturn.ToList().ForEach(ev => ev.CurrentEventDate = ev.EventDates.Where( evd => evd.StartDateTime.Date <= qDate.Date && evd.EndDateTime >= qDate.Date).Single()); return toReturn.AsQueryable(); }

But when I try to look at this object in Javascript, it tells me that:

Error: "CurrentEventDate" is null or not an object

How can I get custom properties after they have been sent by cable?

Make sure that both partial class definitions are in the same namespace. Otherwise, the compiler will turn them into two separate classes and will not warn you.

Just a long shot - EventDate seems to be a normal time. If so, have you decorated it with the Serializable and DataContract attributes (and its properties with the DataMember attribute)?
