Now Microsoft 'decouples' Longhorn from .NET

More code overboard

A security architecture touted as one of the core benefits of Microsoft's next major Windows upgrade look like being the next casualty of the Longhorn death march.

Mary Jo Foley reports that only some parts of Longhorn will be based on .NET 2.0, rather than the entire OS, as originally intended. If this latest bout of indigestion is true, developers gain compatibility at the expense of the superior developer environment of .NET.

But the casualty, as we predicted a year ago, looks like being the ground-up Managed Code architecture which forbids one process from hijacking another: a favorite ploy of malware. (Managed Code is very succinctly summarized here.) So Managed Code is a good thing: a key weapon in the war against viruses.

It's long been rumored as a casualty, as we wrote in May 2004 -

"All of this points to the Managed Code API project being offshored to somewhere closer to Siberia, and more modest lock-downs, such as No Execute pages (due to appear in XP Service Pack 2) being promoted as a good-enough answer."

Mary Jo reminds us that last summer Microsoft "decoupled" WinFS search and storage technology from Longhorn and out into a service pack, throwing in the sweetener for corporates reluctant to upgrade that the Avalon UI libraries would be available on XP. Now she wonders if the latest roadmap modification will be publicly acknowledged.

We think it will. Probably with a press release entitled "Longhorn Promises Greater Compatibility" with the task of imagining the additional words "than we originally planned" being left as an exercise for the reader. ®
