Pushing Data to a Silverlight Client with Sockets: Part I

Silverlight 2 has built-in support for sockets which creates some interesting possibilities. If you've ever worked on a client-side application that needed to receive up-to-date data then you're probably used to solving the problem by polling. With polling the client contacts the server on a consistent, timed basis to see if any updates are available. ASP.NET AJAX provides a Timer control that makes this process easy and straightforward.
