We’re interested in adding support for scheduling cancellation. For example: // Create a token source that will Cancel() after a delay var cts = new CancellationTokenSource(TimeSpan.FromMilliseconds(100));// And/or schedule a Cancel() call cts.CancelAfter(TimeSpan.FromMilliseconds(100));We’ve heard from many folks that ...
As mentioned here, the Visual Studio Async CTP is now available for download from https://msdn.com/vstudio/async. Not only does this download add language support into C# and Visual Basic for writing asynchronous methods (in which you can easily “await” tasks), it also includes a new .NET library we lovingly refer to as “TPL...
Today is a very exciting day for Parallel Extensions, and indeed for all developers using C# and Visual Basic and who are interested in writing more responsive and scalable applications. At the PDC this morning, Anders Hejlsberg just announced the Visual Studio Async CTP, which you can download immediately from the landing page at https://msdn.com/...
We’ve been considering adding a Values property to System.Threading.ThreadLocal<T>. Values would return a collection of all current values from all threads (e.g. what you’d get if you evaluated Value from each thread). This would allow for easy aggregations, and in fact in our Parallel Extensions Extras we have a wrapp...
We’ve seen a number of folks write the following code to execute on the UI thread and get unexpected behavior. TaskScheduler uiScheduler = TaskScheduler.FromCurrentSynchronizationContext();Task uiTask = Task.Factory.StartNew(delegate{ // … Update UI component; BUG!}, uiScheduler);The issue is that the StartNew ca...
Joe Albahari, author of "C# 4.0 in a Nutshell", has just published on his Web site the material from his book covering Parallel Extensions. You can find his extensive article here:https://www.albahari.com/threading/part5.aspxNice work, Joe.
It's exciting to see that the Microsoft Biology Foundation 1.0 has been released! You can read more about it here. From MBF's Web site:"The Microsoft Biology Foundation (MBF) is a language-neutral bioinformatics toolkit built as an extension to the Microsoft .NET Framework, initially aimed at the area of Genomics research. Currentl...
The .NET Framework 4 introduces a new mechanism for cancellation of operations, based on new types CancellationToken and CancellationTokenSource. This cancellation mechanism is used across the parallel programming libraries: tasks, concurrent collections, and PLINQ queries.Using Cancellation Support in .NET Framework 4, written by Mike Li...
Many different kinds of applications can benefit from multi-core parallelism, including add-ins to Microsoft Office. Donny Amalo wrote a paper, PLINQ and Office Add-ins, where he demonstrates how to implement two parallel Microsoft Office add-ins using PLINQ: (This paper and many more are available through the Parallel Computing Developer C...
Despite the similarity in naming, the System.Threading.Tasks.Parallel class and the System.Activities.Statements.Parallel* activities in WF4 are largely orthogonal in the scenarios they address. However, WF4 activities and the new parallel programming types in .NET 4 can be used together to great advantage.Ling Wo and Cristina Manu wrote a pap...
