CRUD (Create, Retrieve, Update, Delete) operations in Silverlight

This article describes the simplest way of how to do CRUD (Create, Retrieve, Update, Delete) operations in Silverlight using ADO.NET Data Service (Astoria). There are two ways to communicate with Database in Silverlight. 1) Web Service 2) ADO.NET Data Service. I chose ADO.NET Data Service for this article because RESTful Service and RIA (Rich Internet Application) development are the best match.
