Do any of you have experience doing true BDD (or even TDD) using Microsoft's Test Manager or Coded UI Tests? 

I am not very familiar with these tools as we have been using SpecFlow and WatiN for BDD.
One team in our organization is proposing Test Manager but I fear they are mistaking the ability to write tests with actually doing true BDD/TDD where you write a small test FIRST and THEN write the minimal code to pass the test.

The example they showed us was writing out a test case in Test Manager, firing up the UI and recording what the test does. Obviously, this is NOT BDD. Can true BDD be done with Test Manager?

Any thoughts are appreciated.
Thanks,
Will

Wow, almost a week and no responses. Can I take that to mean that NOBODY uses TestManager because it is a QA tool instead of a developers tool?
