It was subsequently decided that WinFS would ship after the release of Windows Vista, but those plans were shelved in June 2006, with some of its component technologies being integrated into upcoming releases of ADO.NET and Microsoft SQL Server.[4] While it was then assumed by observers that WinFS was finished as a project, in November 2006 Steve Ballmer announced that WinFS was still in development, though it was not clear how the technology was to be delivered.[5] Several components of the last Integrated Storage Initiative project, Microsoft Semantic Engine, presented at Microsoft PDC 2009, have been integrated back into the SQL Server "Denali".
