The 'Dirty Little Secret' About Longhorn: "Contrary to what many believe, Longhorn won't be built on top of the .Net Framework, we hear. But that might not be a bad thing.
Developers say there's a dirty little secret about Longhorn that few Softies are discussing publicly: Longhorn won't be based on the .Net Framework."
I guess I missed the part of PDC 2003 when someone from Microsoft suggested Longhorn was going to be based on the .NET Framework. Yeah WinFX is all about managed code interfaces to platform functionality, but nobody said the operating system would be rewritten atop the .NET Framework.
Second example I've seen so far today of the tech press getting a bit too creative with headlines/stories.
