Microsoft.Extensions.DependencyInjection.Abstractions

About

Supports the lower-level abstractions for the dependency injection (DI) software design pattern which is a technique for achieving Inversion of Control (IoC) between classes and their dependencies.

Key Features

• Interfaces for DI implementations which are provided in other packages including Microsoft.Extensions.DependencyInjection.
• An implementation of a service collection, which is used to add services to and later retrieve them either directly or through constructor injection.
• Interfaces, attributes and extensions methods to support various DI concepts including specifying a service's lifetime and supporting keyed services.

How to Use

This package is typically used with an implementation of the DI abstractions, such as Microsoft.Extensions.DependencyInjection.
