Microsoft. net Framework 3.5 Service Pack 1 is a cumulative update, which contains many. net Framework 2.0, 3.0, and 3.5. net Framework 2.0 Service Pack 2 and. net Framework 3.0 Service Pack 2 cumulative updates.
. NET Framework 3.5 Service Pack 1 provides the following new features and improvements:
-
- ASP. NET Dynamic Data, which provides a rich framework, allows users to quickly develop data-driven, without the need to writeCodeASP. NET Ajax is a new feature that supports managing browser history (supports the back button ). For more information, see what's new in ASP. NET and web development (new features in ASP. NET and web development ).
-
- Core improvements to the runtime of Public languages include: improved the layout of. NET Framework Local images, and no longer selecting fully trustedProgramSet to perform strong name verification, improve application startup performance, improve the generated code to shorten the execution time of end-to-end applications, select aslr (address space layout randomization) run the managed code (if supported by the operating system ). In addition, hosted applications opened from network sharing have the same behavior as local applications when running in a fully trusted environment.
-
- Improves the performance of Windows Presentation Foundation, including shortening the startup time and improving the performance related to the bitmap effect. Other new functions of WPF include: improved support for business line applications, local initial screens, DirectX pixel coloring devices, and added the webbrowser control.
- The clickonce application publisher can decide not to sign or encrypt the clickonce application under appropriate circumstances. developers can programmatically install the clickonce application to display custom signatures, in addition, the clickonce error dialog box supports link to a website with a specific application on the web.
-
- The Entity Framework is developed from an existing set of ADO. NET data access technologies. With the Entity Framework, developers can program relational databases according to the application-specific domain model (rather than the basic database model. For more information, see getting started with the Entity Framework ). The Entity Framework also introduces some other features, including support for new types of SQL Server 2008, default entity graphics serialization, and Entity Data sources. In this version, the Entity Framework supports the new date and file stream functions in SQL Server 2008. Graph serialization helps developers generate a Windows Communication Foundation (WCF) service that models all graphs as data protocols. The Entity Data source provides a traditional data source experience for ASP. NET application builders who want to use the Entity Framework.
-
- Added support for the new date and file stream functions in SQL Server 2008.
- ADO. NET data services framework is composed of a combination of modes and libraries that meet the following conditions: it allows you to publish data as a flexible data service based on rest (Transmission of concrete states, this service can be used by web clients within the enterprise network or the entire internet. ADO. NET data services framework supports creating data services based on any data source. By fully integrating with the ADO. NET Entity Framework, you can easily publish the conceptual view model of the basic storage architecture. You can easily access services created using ADO. NET data services framework and compatible Windows Live (dev.live.com) services from any platform. A set of client libraries are provided for client applications running on Microsoft platform to simplify interaction with data services. For example, A. NET Framework-based client can use LINQ to query data services, or use the simple. NET Framework Object layer to update data in this service.
-
- Now, the Windows Communication Foundation has improved its support for interoperability and enhanced debugging experience in some trusted situations, in addition, the integration protocol support is extended so that more extensive applications can be applied in Web 2.0 applications, making the datacontract serialization program easier to use.
-
- The. NET Framework data provider for SQL Server (sqlclient) adds support for the file stream and sparse column functions in SQL Server 2008.
