Free learning material for Windows Presentation Foundation, Big improvements in the Framework 4.0 material

A useful “What’s New in WPF Version 4”, again a big improvement, all of the links appear to be useful. So check it out.
So what should you do? Sign up for the free Azure 30 day trial, keep in mind that hotmail/live ids are free, so if you need one, just get one. 
Then get your WPF knowledge, which is directly transferable to Silverlight and Windows Phone 7. Use it to connect with Azure.
Sidenote: I get excited easily about technology.
