I ran into the same issue trying to request the latest updates and working around it by doing the following
// defined elsewhere private DateTime lastUpdated; string consult = "select * from WorkItem where [Created Date] > ' " + lastUpdated.ToString("MM/dd/yy") + "' AND [Work Item Type] = 'Test Case'"; IEnumerable<ITestCase> tcc = testManagementTeamProject.TestCases.Query(consult).Where(tp => tp.DateCreated > lastUpdated);
I did something very similar to get the test results.
