I would like to up vote ClickOnce
We ship software to on premise customers which then install and host our apps. Thus we don't know the customer's URL where are app is hosted.

Currently we can update our app.config so our app knows where the hosted services are. Then ClickOnce solves this as we package the ClickOnce app on their server using mage.exe with their own server's URL.
