If you're planning on attending my BFlex session tomorrow on creating AIR application updaters, please click here to download the lab assets we will be using. I will have the files available on USB drives tomorrow but grabbing the assets now will get you all prepared. Be sure to also check out the prerequisites and software requirements on my session page on the BFlex Web site.
If you aren't attending my lab but you are interested in working through the content yourself, you can also download the assets. I've included my slides, a 30-page step-by-step instructions doc, and all the source code.
Update: September 12, 2010
Thanks to Joey from Nashville for pointing out I forgot to include the instructions doc in the download. I've fixed this and uploaded new download assets.
