Hi Radoslaw
WinFS Beta 2 will have some substantial changes to the data model and
programming surface. Specifically, our entire containment / composition
model has been revised. We also have revised how links work. The bottom
line is that the Beta 1 schemas and applications will not be compatible with
Beta 2. On the API side, we are eliminating Opath and adopting the full
ADO.NET vNext surface.
The Beta 2 API will be very close to our final API. We do not paln for
major changes to occur between Beta 2 and RTM.
Beta 2 will also not be released in 2006 Q2. It will be released later this
year.
ADO.NET vNext has support for a part of the LINQ technologies called DLINQ.
ADO.NET vNext applications will be able to embed DLINQ in their applications
to interact with the data store tiers. By integrating with the ADO.NET API,
WinFS will inherit all of those capabilites.
Cheers!
