The .NET Framework 3.5 Service Pack features new abstractions for working with data, smaller client profiles and performance updates to Windows Presentation Foundation (WPF). It will ship before the end of the summer, Microsoft said. In a July 31 meeting with SD Times, Shanku Niyogi, product unit manager of the UI Framework and Services team at Microsoft, said that .NET Framework 3.5 Service Pack 1 (SP1) would be broadly available in all localized versions “within a few weeks.”
SP1 adds support for SQL Server 2008, the ADO.NET entity framework and ADO.NET data services, which was formerly known as “Astoria.”
Astoria uses ADO.NET to model data, and it exposes entities as URI-addressable resources to be consumed by Web clients within corporate networks and across the Internet. The entity model provides developers with an additional layer of abstraction between the database and themselves.
