A couple of days ago I spent some time trying to find how to make Unity call a factory method when user requests an object. Then I forgot about it, and tried to Google it again. This stuff is surprisingly hard to find, especially given the fact that the method used in Unity 1.x (StaticFactoryExtension) was declared obsolete in favor of InjectionFactory which for whatever reason Unity authors consider “much easier” to use.
Anyway, here’s a full working example, mostly for my future reference:
using System;
using Microsoft.Practices.Unity;
namespace UnityObjectFactory
{
class Program
{
static void Main(string[] args)
{
var container = new UnityContainer();
var factory = container.Resolve<OrderFactory>();
container.RegisterType<IOrder>(
new InjectionFactory(unused_container=>factory.CreateOrder()));
var order1 = container.Resolve<IOrder>();
Console.WriteLine("Fisrt order has number " + order1.Number);
var order2 = container.Resolve<IOrder>();
Console.WriteLine("Second order has number " + order2.Number);
}
}
interface IOrder
{
int Number { get; }
}
class Order : IOrder
{
public Order(int number) { Number = number; }
public int Number { get; private set; }
}
class OrderFactory
{
int _lastOrder;
public IOrder CreateOrder()
{
return new Order(++_lastOrder);
}
}
}

Fascinating blog! Is your theme custom made or did you download it from somewhere?
A theme like yours with a few simple adjustements would really make my
blog stand out. Please let me know where you got your design.
Thanks a lot

The theme is called “boxy but gold”, downloadable from WordPress web site (or at least it used to be).

Do you have a spam issue on this blog; I also am a blogger, and I was curious about your situation;
many of us have created some nice practices and we are looking to
exchange techniques with others, why not shoot me an email if

Hi there! I realize this is kind of off-topic but I needed to ask.
Does managing a well-established website such as yours require a lot of work?
I am completely new to blogging but I do write in my diary daily.
I’d like to start a blog so I will be able to share my personal experience and feelings online. Please let me know if you have any kind of recommendations or tips for new aspiring blog owners. Thankyou!
