“As promised earlier this month, Microsoft announced today that both Visual Studio 2008 and the accompanying .NET Framework 3.5 have been released to manufacture (RTM).
Codenamed Orcas, Visual Studio 2008 (VS2008) comes two years after Visual Studio 2005. In total, there are more than 250 new features added with significant enhancements across every version ranging from Express Editions to Visual Studio Team Systems (VSTS). A key addition in VS2008 is support for the new Language Integrated Query (LINQ), which is positioned as a technology for rapid application development. LINQ is designed to let developers focus on what they need the data to do, rather than be mired in the complexities of data abstraction and casting. Also, LINQ makes it easier to tie C# or Visual Basic with SQL.” – Source
