OK, so I started going down the road of creating a silverlight web application using the Silverlight Business Application template of Visual Studio 2010. After about 4 hours trying to configure things straight with the authentication credentials and styling on the application, I decided to give up and start with my own WCF-from-scratch entity service layer to serve data to my clients. Cheez, sometimes you really need simplicity. RIA Services provides a lot of nice wrappers with the Domain Services WCF wraps, but the template itself is not very easy to adapt to your own model. Maybe later I’ll take a second look at the RIA template with VS 2010, but for now, I’m going rogue old style project by project.
