Today 2 new SP1′s arrived on the scene. One for Visual Studio 2008 and one for Microsoft’s development .NET3.5 framework. It’s a good thing too, the framework has some cool enhancements for the traditional languages like C#, VB but also for WPF, ASP.NET 3.5 etc..
.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 Whatâ€™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.

ASP.NET in the .NET Framework 3.5 Service Pack 1 release includes numerous bug fixes. In addition, it includes features for the following:
- Enabling high-productivity data scenarios by using ASP.NET Dynamic Data.
- Supporting the browser navigation in ASP.NET AJAX applications by using ASP.NET AJAX browser history.
- Increasing the download speed for ASP.NET applications by using ASP.NET AJAX script combining.

I’m also very happy with the SP1 for Visual Studio 2008. I wanted to try out SQL Server 2008, which came out a couple days ago. But there seems to be a problem when you try to install SQL Server 2008 with Visual Studio 2008 (without SP1). They have conflicting components. If you check out the release notes of SQL Server 2008 you can see that Visual Studio 2008 SP1 is a requirement for SQL Server 2008.
One other tip I have to give you is that if you want to install Visual Studio 2008 SP1 and you have beta version of the service pack, please download an use the Visual Studio 2008 Service Pack Preparation Tool. This tool deletes all those previous versions.
Ok so now you have all the necessary information so go ahead and:
Download Visual Studio 2008 SP1 (which also installs .NET 3.5 SP1)
Download .NET 3.5 SP1
