What is the RSS support in Windows Vista?
That's a short question with a long answer. In as few words as possible: Microsoft is building support into Windows Vista to enable application developers to integrate RSS into their applications and create amazing experiences for their users. For the longer answer, see the scenario and architecture document that's available on this site.
When will application developers begin to actually work with this? When the first beta of Windows Vista is released or at PDC?
We are making specifications and an architectural overview available for developers and content publishers to begin exploring these new capabilities now. Basic end-user RSS functionality will be available in Windows Vista Beta 1, scheduled for release this summer. The RSS support in the Windows Vista platform will be discussed in detail at Microsoft Professional Developers Conference (PDC) in September, and PDC attendees will be provided with early versions of the software so they can begin exploring how to build RSS support into their applications.
