        {
            var manager = new EntityManager(_serviceName);

            // Metadata must be fetched before CreateEntity() can be called
            await manager.FetchMetadata();

            // Ensure there is at least one active todo item named Wine in the database
            var wines = await new EntityQuery<TodoItem>().Where(td => td.Description == "Wine" && !td.IsArchived && !td.IsDone).Execute(manager);
            if (!wines.Any()) {
                var newWine = manager.CreateEntity<TodoItem>(new {Description = "Wine"});
                await manager.SaveChanges();
            }
            manager.Clear();

            //Snippet1

            var allTodos = await manager.ExecuteQuery(query1);
            Assert.IsTrue(allTodos.Any(), "No TodoItems in the database");
            
            //Snippet2
            var query2 = query1.Where(td => !td.IsArchived);
            var unarchivedTodos = await manager.ExecuteQuery(query2);
            Assert.IsTrue(unarchivedTodos.Any(), "No unarchived TodoItems in the database");

            //Snippet3
            var query3 = query1.Where(td => !td.IsArchived && !td.IsDone);

            var wineTodos = await manager.ExecuteQuery(query4);
            Assert.IsTrue(allTodos.Any(), "No Wine TodoItems in the database");

            //Snippet5
            // Execute above query locally
            var localWineTodos = manager.ExecuteQueryLocally(query4);
            Assert.AreEqual(wineTodos.Count(), localWineTodos.Count(), "Got " + localWineTodos.Count() + " local wine TodoItems");
