I wasn't kidding about all of the cool stuff happening as soon as I'm gone! On Monday afternoon an updated version of the Silverlight 1.1 Tools Alpha was released. This version will work with the RTM version of Visual Studio 2008.
This means that all the great features you know and love from Silverlight Tools will work in the released version of Orcas, including Xaml intellisense, debugging support, compatibility with Expression Blend, code-behind intellisense and support for Silverlight 1.1 projects.
All of this can be downloaded here for free. If you're looking for tutorials, the Silverlight.net site has some great ones here.
Give it a try, and let me know what you think - I'm interested in early feedback on people's experiences with Silverlight, especially 1.1 apps. Have fun!
