Dependency injection is a design pattern where components are given their dependencies rather than creating them.

• In .NET, dependency injection is implemented using built-in IoC containers like Unity, Autofac, or Ninject.

• Dependencies are registered in the container and injected into the classes that need them.

• This helps in decoupling components, making the code more maintainable and testable.

• For example, in ASP.NET Core...read more

State management techniques in Flutter help manage the state of widgets and data throughout the app.

• Provider package: A simple way to manage state in Flutter using InheritedWidget.

• Bloc pattern: Helps separate presentation and business logic, making it easier to manage state.

Parallelism involves executing multiple tasks simultaneously, while concurrency involves switching between tasks in a timely manner.

• Parallelism is suitable for tasks that can be truly executed simultaneously, while concurrency is more suitable for tasks that involve waiting for external events or resources.

• Parallelism can lead to better performance in tasks that can be divided into independent subtasks, while concurren...read more
