Silverlight – What, when, where, how, and why

This is multi part post. Odds are I will just keep adding to it…

What
Microsoft Silverlight is a cross-browser, cross-platform, and cross-device plug-in for delivering the next generation of .NET based media experiences and rich interactive applications for the Web. I first noticed it appear via update in Q2 2008 on machines. It has an official site where you can learn and see what it can do here: http://silverlight.net/
