我可以使用任务并行库在.NET 3.5的项目？ [英] Can I use the task parallel library in a .Net 3.5 project?

问题描述

我听说任务并行库可以在.NET 3.5的项目中使用。这是正确的，如果是，我该如何使用呢？在.NET 4.0中，它位于的System.Threading，但是当我选择的.Net 3.5在Visual Studio 2010中的目标，我没有得到访问类，如并行和并行循环。

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.

推荐答案

您无法使用的完全的并行扩展，不...

You can't use the full Parallel Extensions, no...

...但如果​​你安装无扩展了解.NET 3.5，即的comes一个版本并行扩展的，所以你可以使用它。我不知道有多少PFX的支持，但我怀疑有足以让大多数人。 （有在博客中的一些细节，但这是自2009年......我不知道在2010年可能会或可能不会被回迁任何修改。）

... 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.)

请注意，这是不支持的，太 - 也许罚款爱好的项目，但如果我想用PFX商用，我想升级到.NET 4

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.
