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!");
}
