I just uploaded the slides & sample application I used in my webinar on Building SharePoint 2010 Silverlight Applications with MVVM by Critical Path Training . The download is available from the Critical Path Training site’s Members section. To access this section you’ll need to be logged into the site. If you don’t have an account, feel free to create one… they are free! Once in, go the the Presentations section and it’s listed as AC’s SP2010-Silverlight-MVVM Product Browser.
Over the next few months I plan to update it to include more features, more comments and capabilities as well as more tests. Enjoy!
