Using Webservices with Telerik OpenAccess

One of the major issues with querying a webservice with the non-domain model approach to OpenAccess was that if you tried to return a list of objects directly you can't dispose of your scope! Ack!

What happens client side is that you get a callback error saying "The ObjectScope is already closed"...bummer I wanted those objects

I had a bunch of tickets go back and forth with the OpenAccess guys at Telerik and they suggested using fetch plans. I however do not want to setup 40 fetch plans :)

So lets use anon typed in-memory objects...they seem to return fine while allowing me to kill my scope.

So from this:

List<ViewAllRequest> returndata = (from r in scope.Extent<ViewAllRequest>()
                                   select r).ToList();

To this:

var returndata = (from r in requests
                  select new {
                      RequestID = r.RequestID,
                      Status = r.Status,
                      ResidentName = r.ResidentName,
                      ResidentEmail = r.ResidentEmail,
                  }).ToList();

So really we're just re-creating the objects, but you can now dispose of your scope before you return from the webservice with no errors!
