At Microsoft we are always looking to get feedback about our products and technologies from communities and influencers. Today we have released the 2nd Community Technical Preview (CTP) for Parallel Extensions to the .NET Framework 3.5. You may want to download it, try it out, let us know what you think, blog about it, and tell your community and customer contacts.    

Parallel Extensions simplifies development by providing library-based support for introducing concurrency into applications written with any .NET language, including C# and Visual Basic. It includes the Task Parallel Library (TPL), which provides imperative data and task parallelism; Parallel LINQ (PLINQ), which provides declarative data parallelism; and all new Coordination Data Structures (CDS), which provide support for work coordination and managing shared state.

 

In addition to CDS, this upgrade provides several improvements, including a new scheduler that is more robust, efficient, and scalable. TPL also exposes new functionality, including methods for continuations. PLINQ now runs on top of TPL, clarifies order-preservation, and provides several new operators.

 

This download works with the .NET Framework 3.5 as a simple, small-footprint installation that drops a single DLL, documentation, samples, and registers the DLL with Visual Studio 2008.

 

We have kicked off this launch with some announcements in various channels, including some posts on our blog.  More posts and announcements will continue to roll through as we build up on rolling thunder toward PDC in October.  More information on Microsoft's Parallel Computing Initiatives are available externally at http://msdn.microsoft.com/concurrency and internally at http://devdiv/sites/pci.  Here are the initial posts to our blog:

Enjoy!
