Inversion of Control in MVC
The document discusses inversion of control (IoC) and dependency injection (DI) in ASP.NET MVC. It explains the SOLID principles, different types of DI like constructor injection and interface injection. IoC inverts control by introducing a container to manage class dependencies rather than the classes directly depending on each other. The document provides examples of using an IoC container to resolve dependencies for an MVC controller and power source for a laptop. It also discusses creating a custom controller factory in MVC.
