Up until now our app has been published using ClickOnce via the Visual Studio "Publish" wizard. This has been rather painful, and we've automated the process using msbuild/mage.
Unfortunately, the new deployment does not appear to be compatible with the old one, giving the "The deployment identity does not match the subscription" error when the (test) users update.
Now there are plenty of differences between the files generated using "Publish" and our Mage script, but we can't eliminate them all. For example, "Publisher" doesn't seem to be respected by GenerateDeploymentManifest, while Mage -New Deployment can't set UpdateMode to Foreground. There are other similar cases.
Has anyone ever successfully moved away from the "Publish" wizard without requiring the entire user base to reinstall the app? What was your approach?
P.S. VisualStudio 2008; all users are on .NET Framework 3.5 SP1.
