CodedUI with MTM as a datasource no longer displays Errors on test failures

Question

Alright, I have 2 simple automated test cases. One, TC1, uses MTM as a data source and the other, TC2, does not. Both are programmed to fail. When the TC1 fails no errors are displayed in MTM Test result but is available in the iTrace. When TC fails, the
assertion error is displayed in MTM.
TC1:
[DataSource("Microsoft.VisualStudio.TestTools.DataSource.TestCase", "http://blah/tfs/blah;blah", "999", DataAccessMethod.Sequential), TestMethod]
public void TestCase1()
String result = TestContext.DataRow["Result"].ToString();
if (result.Equals("Fail"))
Assert.Fail("Test Fails just because I want it to");
}Result in MTM is set to "Fail". The following test result is: TC2:
[ TestMethod]
public void TestCase2()
Assert.Fail("Test Fails just because I want it to");
Result in MTM:So...what's going on here? How do I get the error message to populate when using MTM as a data source? Thanks

Hi Jeffjagen,
Like this case here:

Maybe the test did not run, and hence no error message was there.
