关于WF4 State Machine 状态机工作流的发布问题.

搜了半天, 终于找到了它了下落:

MSDN摘抄:

State machine functionality in Windows Workflow Foundation (WF) was introduced as part of the Microsoft .NET Framework 4 Platform Update 1 (KB2478063). To create state machine workflow applications in Visual Studio 2010, the Microsoft .NET Framework 4 Platform Update 1 – Design-time Package for Visual Studio 2010 SP1 (KB2495593) is required. For more information and instructions on how to download and configure these updates, click here.

总结得出下面的结论:

1.VS2010里没有State Machine, 只有Sequence和FlowChart两种工作流, State Machine没有随VS2010发布.

2.WF4 State Machine已经结束CTP, 现在已经正式发布了, 存在.NET Framework 4 Platform Update 1中, 如果要装.NET Framework 4 Platform Update 1, 您得先装VS 2010 SP1, 大约1.4G, 可能仅能在线安装.

3.State Machine在.Net 4.5中被正式的包含了进去.
