Implementing DIP in .NET Core

• Create an interface for the dependency

• Implement the interface in a separate class

• Inject the dependency into the consuming class

• Use dependency injection container to resolve dependencies

Compile time polymorphism is achieved through function overloading and templates, while run time polymorphism is achieved through virtual functions and inheritance.

• Compile time polymorphism is resolved at compile time, while run time polymorphism is resolved at run time.

• Function overloading is an example of compile time polymorphism, where multiple functions with the same name but different parameters are defined.

• Templates are another example of compile time polymorphism, whe...read more

There are three types of LifeTime Scopes in Dependency Injection: Transient, Scoped, and Singleton.

• Transient: Objects are created each time they are requested.

• Scoped: Objects are created once per request.

• Singleton: Objects are created only once and shared across the application.

Compile time polymorphism is method overloading while runtime polymorphism is method overriding.

• Compile time polymorphism is resolved at compile time while runtime polymorphism is resolved at runtime.

• Method overloading is an example of compile time polymorphism where multiple methods have the same name but different parameters.

• Method overriding is an example of runtime polymorphism where a subclass provides its own implementation of a method that is already defined in its sup...read more

Abstract classes can have both abstract and non-abstract methods, while interfaces can only have abstract methods.

• Abstract classes can have constructors, fields, and methods, while interfaces cannot.

• A class can only extend one abstract class, but it can implement multiple interfaces.

• Abstract classes are used to define a common behavior for subclasses, while interfaces are used to define a contract for classes to implement.

• An abstract class can have method implementations, whi...read more

Compile-time polymorphism is method overloading while runtime polymorphism is method overriding.

• Compile-time polymorphism is resolved at compile-time while runtime polymorphism is resolved at runtime.

• Method overloading is an example of compile-time polymorphism where multiple methods have the same name but different parameters.

• Method overriding is an example of runtime polymorphism where a subclass provides its own implementation of a method already defined in its superclass....read more

Object oriented principles are a set of programming concepts that focus on objects and their interactions.

• Encapsulation - bundling data and methods that operate on that data within a single unit

• Inheritance - creating new classes from existing ones, inheriting their properties and methods

• Polymorphism - ability of objects to take on many forms, allowing for flexibility and extensibility

• Abstraction - hiding implementation details and exposing only necessary information to the us...read more

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

• Allows for easier testing by mocking dependencies

• Promotes loose coupling between components

• Improves code reusability and maintainability

• Example: Constructor injection, Setter injection, Interface injection
