Microsoft 在 .NET 4.0 中重写了 Windows Workflow Foundation 吗？
我听朋友说微软再次重写了所有的Windows Workflow Foundation（WF），并在.Net 3.5中改变了一切。
真的吗？
那么我们在 3.0 和 3.5 中对 WF 的了解又如何呢？
I heard from a friend that Microsoft rewrote all the Windows Workflow Foundation (WF) again and changed everything was in .Net 3.5.
Is that true?
And what about what we learned about WF in 3.0 and 3.5?

根据这篇文章：
http://visualstudiomagazine.com/ articles/2009/01/01/windows-workflow-changes-direction.aspx
Windows Workflow Foundation 4.0 是“采用全新思维的自下而上重写...WF 3.0/3.5 将保留为框架的一部分，并且将与 WF 4.0 并行运行，这使您可以在适合组织更广泛目标的时间管理过渡。”
...这是代码，“我们知道我们刚刚搞砸了您的编程模型，但我们有长期战略，所以我们希望您能原谅我们。”
文章接着说
这一变化并非没有批评者。 在 DotNetKicks 上的这篇文章中，作者指出“微软正在严重损害 Dot Net 开发者社区，并且由于这些半成品产品的发布和发货后的突然转变，该行业的采用率很高。”
这就是为什么我通常等待 Microsoft 技术的 2.0 或 3.0 版本，尽管我对 ASP.NET MVC 进行了例外处理。
According to this article:
http://visualstudiomagazine.com/articles/2009/01/01/windows-workflow-changes-direction.aspx
Windows Workflow Foundation 4.0 is a "bottom-up rewrite with entirely new thinking...WF 3.0/3.5 will remain part of the framework and will run side by side with WF 4.0. This lets you manage the transition at a time that fits your organization's broader goals."
...which is code for, "We know we just screwed up your programming model, but we have a long term strategy, so we hope you will forgive us."
The article goes on to say that
The change is not without its detractors. In this article at DotNetKicks, the author states that "Microsoft is seriously damaging the Dot Net developer community and adoption in the industry with these half baked product releases and abrupt about-faces after shipping."
Which is why I generally wait for the 2.0 or 3.0 version of Microsoft technologies, although I made an exception for ASP.NET MVC.
我们发现，当需要传入和传出数据时，工作流程产品很难让您理解。 斯科特·艾伦（Scott Allen）有一系列文章很好地描述了这个过程，但这仍然不是一件容易的事。
We found the workflow product to be difficult to wrap your head around when it came time to pass data in and out. Scott Allen had a series of articles that did a good job describing the process, but still this was not at an easy task.
这就是街头流传的说法 是。 以及互联网。 3.0 和 3.5 将被弃用，但仍然可用。
That's what the word on the street is. And on the internet. 3.0 and 3.5 will be deprecated, but still available.
Visual Studio 2010 beta 1 中没有此更改吗？ 下载它，了解一下，然后告诉 Microsoft 您的想法。
