I thought about using an existing one, and then there are so many great tools already available, but the sole reason behind building a custome one is to learn few stuff and see it for one self.

Having said that, I was reading this timeless piece.

• Constructor Injection
• Setter Injection
• Interface Injection

And as well, about the Service Locator. Hopefully, i should be able to support at least the bulletted list some time.

Happy Coding!
