Pie Chart in Silverlight with WCF - (Part 1 of Many)

Silverlight:
This is a web development tool created by Microsoft to compete with the Adobe Flash player and its plugin. In my view it is almost getting there. To my knowledge we can do anything and everything that we can possibly do in flash (using action script).
Silverlight is quite a recent technology, released in 2007 as Silverlight 1.0 and now in just 2 year we have a very advanced version Silverlight 3.0. For me it used to be touch to program in Silverlight 1.0 where I know I can do great stuff, but the way we had to do is different than it is now. Microsoft also came up with a new suite called “Microsoft Expression” a combination of design and development tool for web designing and development. An Application called “Microsoft Expression Blend” which is a tool that makes our job much easy to develop a Silverlight Application.
Lets stop talking about the history and jump into the project.
