Pretty much all of the tutorials/introductions to Windows Workflow Foundation seem to be targeted at versions prior to 4.0, or are somewhat simplistic and don't really show me anything about WHAT the real strengths of Workflows are.
Could someone point me in the direction of some slightly meatier tutorials (clearly my google-fu is failing me), as Workflow is one of the things that I've seen the templates for in VS but never had the time or inkling to have a play with until now.
Note: No video tutorials/introductions/guides, please. I find them impossible to learn from.
