⛓️‍💥 CodeOfChaos.Extensions.DependencyInjection ⛓️‍💥

CodeOfChaos.Extensions.DependencyInjection is a library that provides tools for automizing dependency injection in .NET projects. It includes source generators for automatic registration of services and attributes to facilitate DI.

Features

• Automatic Service Registration: Use source generators to automatically register services in your project.
• Custom Attributes: Define custom attributes to specify the lifetime and other details for your services.

Getting Started

Prerequisites

• .NET 9.0 or later

Installation

You can install CodeOfChaos.Extensions.DependencyInjection via NuGet Package Manager:

dotnet add package CodeOfChaos.Extensions.DependencyInjection

You can install CodeOfChaos.Extensions.DependencyInjection.Generator via NuGet Package Manager:

dotnet add package CodeOfChaos.Extensions.DependencyInjection.Generator

Usage

Define Services with Attributes

You can use the provided attributes to define services:

• InjectableService: Simple attribute to register a class to the implementation which is inserted as a type generic.

  public interface IExampleService;
  
  [InjectableService<IExampleService>(ServiceLifetime.Singleton)]
  public class ExampleService : IExampleService {
      // ...
  }
  

• FactoryCreatedService : Marks the class as a service which creation depends on another injected service.

  • The factory service must implement IFactoryService<>

  public interface ICreatedService;
  
  [FactoryCreatedService<IExampleFactory, ICreatedService>(ServiceLifetime.Transient)]
  public class CreatedService : ICreatedService;
  
  // The above service is something that is created by the Factory service
  
  [InjectableService<IExampleFactory>(ServiceLifetime.Singleton)]
  public class ExampleFactory : IExampleFactory {
      public ICreatedService Create() => new CreatedService();
  }
  
  public interface IExampleFactory : IFactoryService<ICreatedService>;
  

• PooledInjectableService : Marks the class as a poolable service. This library creates a class AutoPoolableService under which the class will be registered.

  • It uses PooledInjectableServiceObjectPolicy to create a policy.
  • The poolable service must implement PooledInjectableServiceObjectPolicy

  public interface IExamplePooled : IManualPoolable; 
  
  [PooledInjectableService<IExamplePooled, ExamplePooled>]
  public class ExamplePooled : IExamplePooled {
      public bool Reset() => true;
  }
  

Generate Service Registrations

The source generator will automatically create the necessary registration code. C all the generated registration method in your Startup or Program class:

using Microsoft.Extensions.DependencyInjection;

var services = new ServiceCollection();
services.RegisterServicesFromYourAssemblyName();
