Few months back, i was new to web development. I started with ASP.NET to be my first IDE to work on. And as the time passes, i got more interested in presenting. Because an idea and the way of presentation with simplicity does matter. Besides learning other things, i started searhing for silverlight as well over web. And frankly speaking, i was impressed alot from it but was taking as a really hard job to do. But i was wrong, silverlight provides an awesome 3d engine which are so easy to implement. I am sure it would give you a boost in you website if you will use it, and using it is not an issue for the beginner if one knows programming well.
Anyway, now going towards the first step of installing silverlight, we need to have Microsoft Visual Studio 2008 SP1.
In order to start working with Silverlight, its tools should be installed which brings up with a new tab of toolbox in Visual Studio.
