                PublishedProject proj2Edit = projCollection.First();
                DraftProject projCheckedOut = proj2Edit.CheckOut();
                ProjectCont1.Load(projCheckedOut.Tasks);

                QueueJob qJob = ProjectCont1.Projects.Update();
                JobState jobState = ProjectCont1.WaitForQueue(qJob, 20);
