Implementing a simple Silverlight Control

I am sure that many of you have read about Silverlight, the latest offering from Microsoft promising the ability to deliver rich interactive applications and media. Silverlight 1.1 Alpha has just been released and with this in mind, I decided to download all the tools required to start using Silverlight. To be honest, I have not spent much time looking into Silverlight 1.0; I just couldn't bring myself to start coding heavily in JavaScript. Version 1.1 gives the ability to perform the 'behind the scenes' coding in languages such as C# and VB.NET (plus others).
