I managed to note on Twitter that I was speaking last night to the San Diego .NET Developers Group.  The session went well, it was an updated version of the presentation I did last year related to working with Boot to VHD and it's usefulness in working with Beta software and in this case actually digging into Visual Studio 2010 Beta 2.  The slides have been updated (and will be again prior to code camp) so for those who are interested here are my slides.  You'll note a couple that are heavy on graphics - yes those are the ones I incorporated from Microsoft materials, I don't make pretty pictures -especially not if my face is in them
