The new CR.NET 2008 book I write will have all this in it. But unfortunately, I haven't had time to research it yet. This is a new feature which is only allowed with the licensing that comes with CR R2 Dev edition. So I have a bit of work to do to figure out the new API and the differences between it and the .NET 2008 API.
Yes, the CR forums are a bit dead. I hope to make this site the premier CR resource on the web. I just hope that people buy my books so that I can keep this up!
