Good workflow foundation samples

Could you please recommend good articles about wofrlow foundation? It would be very good if it will some open source project experience about this technology. My future project will be related to WF and ASP.NET MVC3, so I wish to get some experience before I start the project. Thanks!

EDIT

It would be very helpf开发者_开发技巧ul to get more information certainly about WF4 and Flowchart workflow. Thanks!

I recommend the PluralSight ones:

You can subscribe for 1 month for free with complete access to presentations, videos and samples.

Try these blog post I did or these MSDN resources including the videos I did for the MSDN site.

You should probably start with the tutorials. But there are the official Microsoft samples. There is also an even better collection of links from Scott Guthrie.
