If you are building Windows Workflow Foundation (WF) applications today (and you aren't building Sharepoint Workflows) you should be using WorkflowServiceHost for your hosting environment. Period, end of discussion (oh - well we can have more decision about it - but its a fait accomplis at this point). Especially if you are using WF to implement a service, using .NET 3.5 is a total no brainer. I was doing so the other day using a StateMachineWorkflow hosted in IIS and I was getting an exception.
