.NET Core IServiceCollection: Dependency Injection Explained

The IServiceCollection interface is part of the .NET Core framework and is used for registering and configuring services within an application's dependency injection container.

It provides methods such as AddSingleton, AddScoped, and AddTransient to register services with different lifetimes.

For example, the AddSingleton method registers a service as a singleton, which means that only one instance of the service will be created and shared across the entire application.

The AddScoped method registers a service as scoped, which means that a new instance of the service will be created for each request or scope.

The AddTransient method registers a service as transient, which means that a new instance of the service will be created each time it is requested.

The IServiceCollection interface also allows for configuration of services, allowing you to specify parameters or dependencies that should be passed to the service's constructor.

Overall, the IServiceCollection interface is an essential part of the .NET Core dependency injection system and is used to register and configure services within an application.
