I've just published the first video in a series where I'll be looking at what's new for PivotViewer in Silverlight 5. The first episode covers legacy support for all our existing cxml collections. I'd welcome any and all feedback.
You have my thanks as well. I have a suggestion however; in future videos perhaps you can zoom in on code -- or record in higher resolution. I find the code to be pretty much useless since it can't be read. I tried streaming as well as downloading the mp4 from vimeo.
Thanks again for your work!
