Does NAnt have the ability to install or uninstall a windows service, using the InstallUtil utility or whatever else?
You can call Nant's exec task to call InstallUtil and can pass parameters to install or uninstall a service easily
<target name="install-service">
<exec program="${framework::get-framework-directory('net-2.0')}\InstallUtil.exe">
<arg value="-i" />
<arg value="/name=V1" />
<arg value="C:\Service\SomeService.exe" />
</exec>
</target>
