Castle Windsor – Lifestyles in XML Configuration

I just wanted to discuss the two most commonly used options are Transient or Singleton. There are other options and you can setup your own custom LifeStyles. Well look at the following code now.

using System;
using Castle.Windsor;
using Castle.Windsor.Configuration.Interpreters;

namespace CastleWindsorDemo

    public interface INotifier
        void Notify();

    public class Notifier : INotifier
        private readonly string[] to;
        private readonly string from;

        public Notifier(string from, string[] to)
            this.to = to;
            this.from = from;

        public void Notify()
            // Put code to send to people wishing to be notified here

    class Program
        static void Main()
            WindsorContainer container = new WindsorContainer(new XmlInterpreter());
            INotifier notifier1 = container.Resolve<INotifier>();
            INotifier notifier2 = container.Resolve<INotifier>();



The default is singleton which means that you get the exact same object everytime you request it. Transient means that you get a new object everytime you request one. Heres the XML

<?xml version="1.0" encoding="utf-8" ?>
        type="Castle.Windsor.Configuration.AppDomain.CastleSectionHandler, Castle.Windsor" />
      <component id="notifier"
                 type="CastleWindsorDemo.Notifier,CastleWindsorDemos" lifestyle="singleton">

If you change the lifestyle to transient you get a new object test it out.
