Release Date: 2009-01-07
OS: Win XP/2003/Vista

Microsoft .NET Framework 3.5 Service Pack 1 is a full cumulative update
that contains many new features building incrementally upon .NET
Framework 2.0, 3.0, 3.5, and includes cumulative servicing updates to
the .NET Framework 2.0 and .NET Framework 3.0 subcomponents. Microsoft
.NET Framework version 3.5 Service Pack 1 provides the following

new features and improvements:
ASP.NET Dynamic Data, which provides a rich scaffolding framework that
enables rapid data driven development without writing code, and a new
addition to ASP.NET AJAX that provides support for managing browser
history (back button support). For more information, see What’s New in
ASP.NET and Web Development.
Core improvements to the CLR (common language runtime) that include
better layout of .NET Framework native images, opting out of
strong-name verification for fully trusted assemblies, improved
application startup performance, better generated code that improves
end-to-end application execution time, and opting managed code to run
in ASLR (Address Space Layout Randomization) mode if supported by the
operating system. Additionally, managed applications that are opened
from network shares have the same behavior as native applications by
running with full trust.

Performance improvements to WPF (Windows Presentation Foundation),
including a faster startup time and improved performance for Bitmap
effects. Additional functionality for WPF includes better support for
line of business applications, native splash screen support, DirectX
pixel shader support, and the new WebBrowser control.
ClickOnce application publishers can decide to opt out of signing and
hashing as appropriate for their scenarios, developers can
programmatically install ClickOnce applications that display a
customized branding, and ClickOnce error dialog boxes support links to
application-specific support sites on the Web.

The Entity Framework is an evolution of the
existing suite of ADO.NET data access technologies. The Entity
Framework enables developers to program against relational databases
in according to application-specific domain models instead of the
underlying database models. For more information, see Getting Started
with the Entity Framework. The Entity Framework introduces some
additional features, including support for new SQL Server 2008 types,
default graph serialization of Entities, and the Entity Data Source.


This release of the Entity Framework
supports the new date and file stream capabilities in SQL Server 2008.
The graph serialization work helps developers who want to build Windows
Communication Foundation (WCF) services that model full graphs as data
contracts. The Entity Data Source provides a traditional data source
experience for ASP.NET Web application builders who want to work with
the Entity Framework.
LINQ to SQL includes new support for the new date and file stream capabilities in SQL Server 2008.

The ADO.NET Data Services Framework consists
of a combination of patterns and libraries, which enable data to be
exposed as a flexible REST (Representational State Transfer)-based
data service that can be consumed by Web clients in a corporate
network or across the Internet.


The ADO.NET Data Services Framework makes
data service creation over any data source. A conceptual view model of
the underlying storage schema can easily be exposed through rich
integration with the ADO.NET Entity Framework. Services created by
using the ADO.NET Data Services Framework, and also compatible Windows
Live (dev.live.com) services, can be easily accessed from any
platform. For client applications that are running on Microsoft
platforms, a set of client libraries are provided to make interaction
with data services simple.


For example, .NET Framework-based clients can
use LINQ to query data services and a simple .NET Framework object
layer to update data in the service.
Windows Communication Foundation now makes the DataContract Serializer
easier to use by providing improved interoperability support,
enhancing the debugging experience in partial trust scenarios, and
extending syndication protocol support for wider usage in Web 2.0
applications.
The .NET Framework Data Provider for SQL Server (SqlClient) adds new
support for file stream and sparse column capabilities in SQL Server
2008.
