I presented tonight (10 July 2008) to the Richmond .NET User Group. We had a pretty good turnout, I'm guessing 40 to 45 developers. I gave this same presentation at my office today as a dry run and as a training opportunity within the company. It's so good to see the developer community eager to learn. I've attached my slides and the three demonstrations projects I used in this post. I'll be giving this same presentation to the Charlottesville .NET User Group next Thursday (17 July 2008). The abstract we put on both user group websites follows:

Silverlight is a client-side technology. So it’s not really a part of your SOA strategy, right? You may want to think twice about that. SOAP and WSDL support are coming to the web desktop via Silverlight. And Silverlight has good client support for REST+ JSON/POX and RSS/ATOM-based web services, too. During this discussion, we’ll dive into data serialization, security and cross-domain access policy capabilities inside Silverlight 2 Beta 2. We also talk about the nuances and pitfalls of provisioning your web services for an Internet audience. This presentation will be heavy on coding, demonstration and interactive discussion.
