The Microsoft employee from the SQL Server team, from my earlier post Whidbey Beta 2 Coming Up, was either mistaken about the immediate release of beta 2, referring to Yukon beta 3 being locked down for Whidbey beta 2, or referring to the just released February CTP. (Or he could be right, but I just haven’t allowed enough time yet.)
The February CTP is currently available in MSDN Subscriptions. The Express versions are also available for the general public. The February CTP is build 2.0.50105.0 and reportedly is stable enough to have been released to internal partner teams within Microsoft. The version number suggests it was built the beginning of this year (January 5, 2005).
