All about Async/Await, System.Threading.Tasks, System.Collections.Concurrent, System.Linq, and more…
October 24, 2011Oct 24, 201110/24/11In .NET 4, Task.Factory.StartNew was the primary method for scheduling a new task. Many overloads provided for a highly configurable mechanism, enabling setting options, passing in arbitrary state, enabling cancellation, and even controlling scheduling behaviors. The flip side of all of this power is complexity.
October 3, 2011Oct 3, 201110/3/11The October 2011 issue of MSDN Magazine is now available online. In it, you can find three articles about the new async/await features of C# and Visual Basic. While the articles can stand alone, they were written with each other in mind in order to provide a 1-2-3 on-ramp into the world of asynchronous programming with these new language and library features.
October 2, 2011Oct 2, 201110/2/11Consider a type that will print out a message when it’s finalized, and that has a Dispose method which will suppress finalization:
class DisplayOnFinalize : IDisposable { public void Dispose() { GC.SuppressFinalize(this); } ~DisplayOnFinalize() { Console.WriteLine(“Finalized”); } }
Now consider a simple usage of this class:
void Foo() {
October 2, 2011Oct 2, 201110/2/11“Don’t forget to complete your tasks.” That guidance may sound trivial and silly, but I recently saw it as a source of a bug in software written by some very smart folks, and thus thought this would be a good opportunity to remind folks of the imperative.
September 28, 2011Sep 28, 201109/28/11For the .NET Framework 4.5 Developer Preview, a lot of work has been done to improve the Task Parallel Library (TPL), in terms of functionality, in terms of performance, and in terms of integration with the rest of the .NET Framework.
September 27, 2011Sep 27, 201109/27/11It’s been a few months since April when we last released a Community Technology Preview (CTP) of System.Threading.Tasks.Dataflow.dll, aka “TPL Dataflow”. Today for your programming pleasure, we have another update.
As mentioned in “What’s New for Parallelism in .NET 4.5”, System.Threading.Tasks.Dataflow.dll is part of the .NET Framework 4.5 Developer Preview released last week at the BUILD conference.
September 18, 2011Sep 18, 201109/18/11Thanks to everyone who attended my two talks at BUILD this past week, and I hope you enjoyed the sessions! For those of you unable to attend in person, the recordings of the talks are now available on Channel9:
Building parallelized apps with .NET and Visual Studio
The zen of async: Best practices for best performance
There were hundreds of other sessions this week at BUILD,
September 17, 2011Sep 17, 201109/17/11.NET 4 and Visual Studio 2010 saw the introduction of a wide range of new support for parallelism: the Task Parallel Library (TPL), Parallel LINQ (PLINQ), new synchronization and coordination primitives and collections (e.g. ConcurrentDictionary), an improved ThreadPool for handling parallel workloads,
