Question

This is driving me mad, I’ve got a DomainService call which on the server contains an Include() to return child objects as follows:

public IQueryable<RegionBorder> GetRegionBordersWithPolygonsAndLatLongs()
    {
        return this.ObjectContext.RegionBorders.Include("RegionPolygons.LatLongs");
    }

I’ve set this line as a debug point on the server and it is generating the correct results with the child collections included within the toplevel entities. However, on the client, I cannot access the children. The client code is as follows:

EntityQuery<RegionBorder> query = idc.GetRegionBordersWithPolygonsAndLatLongsQuery();
        LoadOperation<RegionBorder> lo = idc.Load<RegionBorder>(query);
        lo.Completed += delegate(object sender, EventArgs e1)
        {
            //regionBorders = idc.RegionBorders;
            string prtyName = "ProjOverspend";
            var elements = new Collection<FrameworkElement>();
            var propertySet = new ExtendedPropertySet();
            propertySet.RegisterProperty(prtyName, prtyName, typeof(double), 0d);

            foreach (RegionBorder ent in idc.RegionBorders)
            {
                foreach (RegionPolygon rp in ent.RegionPolygons)
                {
                    Telerik.Windows.Controls.Map.MapPolygon mp = new Telerik.Windows.Controls.Map.MapPolygon();
                    mp.Points = rp.Points;
                    elements.Add(mp);
                    SetExtendedProperty(propertySet, prtyName, mp, 0d);
                }
            }

Can anybody help me with where I am going wrong because I am sure this was working fine before and now just will not do anything.

Thanks for any help.

You have to add IncludeAttribute in metadata as well.
