Types of Dependency Injection As you have seen above, the injector class injects the service (dependency) to the client (dependent). The injector class injects dependencies broadly in three ways: through a constructor, through a property, or through a method.Constructor Injection: In the constructor injection, the injector supplies the service (dependency) through the client class constructor.Property Injection: In the property injection (aka the Setter Injection), the injector supplies the dependency through a public property of the client class.Method Injection: In this type of injection, the client class implements an interface which declares the method(s) to supply the dependency and the injector uses this interface to supply the dependency to the client class.

.NET supports the dependency injection (DI) software design pattern, which is a technique for achieving Inversion of Control (IoC) between classes and their dependencies. Dependency injection in .NET is a built-in part of the framework, along with configuration, logging, and the options pattern..NET Core provides Built in Dependency Injection.

In.NET Core, dependency injection is implemented using the IServiceProvider interface.

In object-oriented programming (OOP) software design, dependency injection is the process of supplying a resource that a given piece of code requires. The required resource, which is often a component of the application itself, is called a dependency.
