Today I stumbled upon another WF4 blog with some quality content, so here is my unsolicited and personal recommendation to - if you are thinking about the how-to-host aspects of WF4 - to take a few minutes gaining some insights on how and why WorkflowServiceHost can be a good building block for your enterprise (or not so enterprise) workflow hosting needs, and what you can do to bridge the gap between hard WF4 programmer stuff, and a easy user-friendly experience for the non-programmers.
