If you’ve been following the development of the Task Parallel Library (TPL), or if you’re an avid reader of this blog, you’re likely aware that the default scheduler in TPL is based on the new and improved ThreadPool in .NET 4.  In light of this, though, quite a few folks have asked whether there are any advantages (...

The meaning of TaskStatus

Stephen Toub - MSFT
Every System.Threading.Tasks.Task instance goes through a lifecycle, and it only makes this journey once.  To provide insight into where in that lifecycle a given Task is, the Task class provides an instance Status property.  That property returns a value from the TaskStatus enumeration that reflects the current point in the ...

Implementing Parallel While with Parallel.ForEach

Stephen Toub - MSFT
The Parallel class in .NET 4 includes methods that implement three parallel constructs: parallelized for loops (Parallel.For), parallelized foreach loops (Parallel.ForEach), and parallelized statement regions (Parallel.Invoke).  One of the interesting things about Parallel.Invoke is that, in some cases and at least in the current ...

Parallel Extensions and I/O

In this post, we’ll investigate some ways that Parallel Extensions can be used to introduce parallelism and asynchrony to I/O scenarios. Here’s a simple scenario.  I want to retrieve data from a number of web resources. static string[] Resources = new string[] {     "http://www.microsoft.com", "http://www.msdn.com", &...
