Playing with Silverlight

I have been working on Silverlight beta 1 for past couple of weeks to prepare a functional prototype (POC: Proof of concept). I just got done with it, I worked with lots of XAML and Javascript and a bit of design related stuff using ExpressionBlend 2 (May preview). It was a good experience to say the least.But one thing that bothered me most was the lack of documentation on Silverlight (WPF/E). Though I understand that the technology is rather new. But i believe when a release is in beta it should be supported by complete API documentation. On the other hand I must say demos have been useful for me to undestand things as they work.
I hope to do more work with Silverlight!
