Accessing SharePoint Data with the Silverlight Client Object Model

The SharePoint Silverlight Client Object Model (Client OM) allows developers to interact with SharePoint from their Silverlight application easily - without having to write and deploy server-side code and without having to depend on the SharePoint web services and their inherent limitations and complexity. This demo will show basic interaction between a Silverlight application and SharePoint list data - specifically focusing on creating, reading, updating and deleting SPListItems directly from Silverlight and without requiring any server-side code.
