Windows Workflow, WCF Ria services & Silverlight Example

I'm looking for an example of using Windows Workflow as a server-side 'business logic' layer, with WCF 开发者_Go百科RIA services handling the communication to and from a Silverlight UI. Been googling for examples, but can't seem to find any. If anyone can point me to a resource, I'd sure appreciate it.

Thanks.
