About

System.Composition.Hosting is part of the Managed Extensibility Framework (MEF) 2.0, a composition library for .NET that enables dependency injection through attributes or conventions.

This package provides core services for creating composition containers. It offers tools to configure and manage the composition of parts within your application, facilitating dependency injection and enabling modular architectures.

Key Features

  • Create and manage composition containers for dynamic dependency injection.

How to Use

Create a composition host and compose parts.

using System.Composition;
using System.Composition.Hosting;

// Create a container configuration
var configuration = new ContainerConfiguration()
    .WithPart<Service>();

// Create the composition host (container)
using CompositionHost container = configuration.CreateContainer();

// Get an instance of the service
var service = container.GetExport<IService>();
service.Run();
// Service is running!

public interface IService
{
    void Run();
}

[Export(typeof(IService))]
public class Service : IService
{
    public void Run() => Console.WriteLine("Service is running!");
}
