I heard that the Task Parallel Library can be used in a .Net 3.5 project. Is this correct, and if yes, how do I use it? In .Net 4.0, it resides in System.Threading, but when I select .Net 3.5 as the target in Visual Studio 2010, I don’t get access to classes like Parallel and the Parallel loops.
(Legacy answer – it seems the backport for 3.5 is no longer readily available.)
You can’t use the full Parallel Extensions, no…
… but if you install Reactive Extensions for .NET 3.5, that comes with a version of Parallel Extensions, so you can use that. I don’t know how much of PFX is supported, but I suspect there’s enough for most people. (There are some details in the blog post, but that was from 2009… I don’t know about any changes in 2010 which may or may not have been backported.)
Note that this is unsupported, too – probably fine for hobby projects, but if I wanted to use PFX commercially, I’d upgrade to .NET 4.
