AFAIK you can’t really use ClickOnce end-to-end to deploy a service; there are issues with both the file locations (ClickOnce installs into a user’s profile) and installation (ClickOnce is largely side-effect free).
You can, however, write a service as an exe that can self-install/uninstall from the services list, like so; basically, you write it as as a console exe and handle some command line args, using AssemblyInstaller to [un]install from the current assembly. Another advantage is that the same approach can be used to help debugging, since you can run it from the command line.
