Silverlight 2.0 has left Beta and is RELEASED!!! Get your development tools over at the official site!
One thing of note that I must mention is that Visual Web Developer Express 2008 SP1 is now a SUPPORTED development environment! So you can now develop for Silverlight with the FREE tool!
Although I must say it's gonna hurt a lot since the XAML designer in Visual Studio is definetly not as powerful as Blend itself. Unless they've made some changes to it! I wouldn't know yet, still downloading and installing the new dev bits as I type this in.
Also.. hope the Silverlight Streaming Service gets upgraded soon too.
