WPF or Silverlight - What's the difference?

Silverlight was of course known as WPF/E where E means everywhere. Both use XAML, a form of XML to define controls but WPF is purely for windows while Silverlight runs in the browser on Windows and Macs. Silverlight 3 is out soon, you can download the beta now from the official site and so far I've found nothing bad with it.

Wintellect a company set up by several programmers and authors have published a 69 page white paper on the differences between Silverlight and WPF. it also includes best practices for development on those platforms. I've added it to the free C# Programming E-Books page. There's a lot of meat in these pages- I was impressed with the mouse event table. There's quite a lot of stuff in WPF that's absent in Silverlight and this paper is useful for comparisons.
