I’ve already blog’d about the WPF Toolkit & the WPF Ribbon Preview. One of the things that may not be obvious, is how to get started with the new controls. Buried inside the October 2008 Release page is a set of links for control walkthroughs, a nice Hands-in-Lab, and a helpful blog post explaining how to turn on Visual State Manager support for WPF in Expression Blend. They are real easy to overlook. I didn’t notice them the first time. They are below the download links, after the release notes. Yes, I am one of those guys that usually skips over the release notes and documentation and just starts tinkering. I’ll never learn my lesson:). I’ve provide direct links to those resources in case you missed them too!
