Lightweight Dependency Injection

Medium Article: https://medium.com/@CalumHamilton/how-does-it-work-dependency-injection-186d9432de4c

A super lightweight Dependency Injection (DI) tool offering core functionality, including Constructor Injection and a DI Service.

Features

• Constructor Injection: Allows dependencies to be injected through class constructors, promoting immutability and easier testing.
• DI Service: Provides a centralized service for managing and resolving dependencies across your application.

Installation

The project is available on Nuget as Lightweight.Dependency.Injection (https://www.nuget.org/packages/Lightweight.Dependency.Injection). It can be added via nuget or using dotnet add package Lightweight.Dependency.Injection --version 1.0.1

Usage

Registering Services

To register a service with the DI container:

var dependencyManager = new DependencyManager();
// Register MyService as the implementation for the IMyService interface.
dependencyManager.AddTransient<IMyService, MyService>();
// Register MySingletonService as the singleton implementation for the IMySingletonService interface.
dependencyManager.AddSingleton<IMySingletonService, MySingletonService>();

Resolving Services

To resolve a service the dependency manager needs to be built. Then, services can either be resolved through class constructors, or by calling the dependency manager below as follows:

dependencyManager.Build();
var myService = dependencyManager.GetService<IMyService>();

This retrieves an instance of IMyService from the service provider.
