I just ran into this issue and all the above answers seem to be over complicating things. All you need to do is use the WhenStarted overload that accepts a Func and return false if your internal service bootstrap failed. I don't think hostControl.Stop() needs to be called explicitly.

//Here is bit from inside the .Service() call
s.WhenStarted((YourService svc, HostControl hc) => svc.Start());

//And the svc.Start method would look something like this:
class YourService
{
   public bool Start() {
     //return true if all is well
     //or false if you want service startup to be halted
   }
}
