Brad Abrams has a long list of
credits for the folks who helped him create demos for this MIX session. When
I was at TechEd last June, I saw a totally awesome demo in a WCF Reliablility
session that also had some top talent at Microsoft involved in building the
demo. The Microsoft demos for the Indigo overview talk that has been done a
lot by Ari Bixhorn takes a truckload of equipment and even a mini
support team to run (whereas I had some ho-hum console apps when I did that
at TechEd South Africa). I spend a ridiculous amount of time on my
demos but will never have anything like the ones these guys get to
pull off for their nice shiny sessions. Sheesh.
