Microsoft on Monday issued Service Pack 1 (SP1) updates for both Visual Studio 2008 and the .NET Framework 3.5 developer libraries, offering the expected bug fixes but also adding significant new functionality. The original versions of Visual Studio 2008 and .NET Framework 3.5 shipped in November 2007.

"The service packs continue to address the needs of the developer community by making it even easier to develop applications for the latest platforms, with new features such as the .NET Framework Client Profile for faster deployment of Windows-based applications, multiple enhancements to ASP.NET, and unparalleled support for database application development through the ADO.NET Entity Framework, ADO.NET Data Services and integration with SQL Server 2008," Microsoft said in a statement.

Visual Studio 2008 SP1 offers better performance and reliability, improved Windows Presentation Foundation (WPF) user interface designers, improved support for developing AJAX applications, richer support for JavaScript, and integration with SQL Server 2008. The product also supports new low-level features of .NET Framework 3.5 with SP1.

With SP1, .NET Framework 3.5 adds support for ASP.NET Dynamic Data, ADO.NET Data Services and the ADO.NET Entity Framework, all of which make it easier for developers to integrate with back-end data sources. Microsoft notes that the update also "improves developer productivity by simplifying the requirements for creating, implementing, changing and scaling applications via delivery of a single framework for service development that spans enterprise-critical applications and emerging rich, interactive applications."

Visual Studio 2008 SP1 and .NET Framework 3.5 SP1 are both free and are now available for download. Both can be found on the Microsoft Web site.
