Learning Windows Workflow Foundation 4, where to start?

I have been playing around with wf4 for a while. I found various articles, videos(channel 9), blog posts and sites about wf4, but couldn't able to organize it in a proper way.

I look forward to create a Learning Catalog for

• Windows Workflow 4 with VS 2010 and IIS 7 (without AppFabric )
• Windows Workflow 4 with VS 2010 and IIS 7 (with AppFabric)

Please help me to create it...

post your answers

• where to start?
• what to learn first?
• must learn topics - in the order of i开发者_如何学编程mportance
• publishing as WCF Service
• hosting

The Windows Workflow Foundation Developer Center is a good place to start.

And if you want to take a course go here (shameless self plug)

I recommend a great book by Bruce Bukovics "Pro WF" (rewritten for WF4). Also check Microsoft's Ron Jacobs online video series.
