Our latest release of the Visual Studio 2010 Training Kit just went live.  The link on the download center is still stale but it should update over the next hour or so.  In the meantime you can download the release directly from here.

 

If you want to hear about how one customer made use of WF4 and VS2010 to build a cool solution, read the Aderant case study.  I hope to have these guys on endpoint.tv in the future to talk more about it.
