We’re very excited that the .NET Framework 4 Beta is now available for public download, as .NET 4 has Parallel Extensions built into its core. You can download the Betas for Visual Studio 2010 and .NET Framework 4 at http://msdn.microsoft.com/en-us/netframework/dd582936.aspx . For more information on what’s new in Beta 1 regarding concurrency and parallelism, here are some useful links: What’s new in Beta 1 for Parallel LINQ (PLINQ)
