So after all, what is Inversion of Control?
Why is there reduction of coupling when using Inversion of Control? What is the application area of Inversion of Control? Are there any cases when you cannot do without Inversion of Control? Is the event model synonymous with the principle of Inversion of Control? What is the difference between libraries and frameworks? Is it possible to follow the principle of Inversion of Control not using the Factory Method, Inversion of Control Container and Dependency Injection?
