Windows服务实现IDisposable – 这是不好的做法？

public class ServiceLauncher2 : ServiceBase,IDisposable

然后这个：

/// <summary>
        /// Disposes the controllers
        /// </summary>
        // This is declared new as opposed to override because the base class has to be able to
        // call its own Dispose(bool) method and not this one. We could just as easily name
        // this method something different,but keeping it Dispose is just as valid. 
        public new void Dispose()
        {
            foreach (var mgr in _threadManagers)
                mgr.Dispose();
            base.Dispose();
        }

我之前从未在Windows服务实现中看到过这种情况.通常只会覆盖OnStop / OnStart.这是不好的做法吗？
