John Robbins attracted my attention a couple of months ago with a series of posts on WiX. More recently I noticed a nice article discussing code signing on the cheap ( and easy ). It’s a good read and I reccomend it. Personally I’ve only signed a few packages with self generated test certificates and then let my customers build the package with their certificates… a sort of design by contract scenario. John’s solution is cheap enough that I might just be tempted to go buy a certificate for myself.
