I have been using the UAB for a while, and have not yet had a chance to play with clickonce within VS2005. I was wondering if anyone knew if it is possible to customise the update process as you can with the UAB, by implementing your own Activation Processor. With the UAB i found this useful as i could create a custom processor to run Database scripts that i had downloaded along with the application files.
Any Ideas
