## 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.
|
||
|
|
|
||
|
