@Kumarkrishna184 Sir,
What is Dependency Injection
Dependency Injection implies sending a dependency into a dependent object as opposed to the dependent object controlling life cycle of its dependencies. It uses a builder object to initialize objects and provide the required dependencies to the object which allows to inject a dependency from outside the class.It is a software design pattern that allow us to develop loosely coupled code
Advantages
- Helps to develop loosely coupled code
- Reduce tight coupling between software components
- Maintainable code
- Unit Testing
For specific to DI in MVC , please refer Sheo Sir's article at DNF :
http://www.dotnetfunda.com/articles/show/3178/simple-controller-dependency-injection-in-aspnet-mvc
What is Unity IOC Container
It is a lightweight DI container for building loosely coupled application that supports constructor injection, property injection, and method call injection.
Advantages
- Easy to create hierarchical object structures and dependencies.
- Support for runtime dependencies.
- Can be easily configured.
- Containers can be cached at the client end.
Please refer to this article as how to use Unity IOC Container in Asp.net MVC :
