I have published a WebAPI service which returns a list of items. I am implementing Breeze and have managed to get it basically working with filtering/sorting. However, the Expand is not working.

http://www.ftter.com/desktopmodules/framework/api/dare/dares/?$filter=DareId%20eq%2010&expand%20eq%20ToUser

You can see the ToUserId ForeignKey in the response above, but the ToUser properties are NULL (the user definitely exists)

You can see the ToUser EF navigation property in the metadata.

When I use .Include on the server side I can populate it with EF, but I don't want to do this.

    [HttpGet]
    [Queryable(AllowedQueryOptions = AllowedQueryOptions.All)]
    public HttpResponseMessage Dares()
    {
        var response = Request.CreateResponse(HttpStatusCode.OK, (IQueryable<Dare>)contextProvider.Context.Dares);
        return ControllerUtilities.GetResponseWithCorsHeader(response);
    }

and here is the generated class from my EF model (using Database First)

public partial class Dare
{
    public int DareId { get; set; }
    public int ToUserId { get; set; }
    public virtual User ToUser { get; set; }
}
