var configuration = new ContainerConfiguration()
    .WithAssembly(Assembly.GetExecutingAssembly());

using CompositionHost container = configuration.CreateContainer();

var handlers = container.GetExports<IHandler>();
foreach (var handler in handlers)
{
    handler.Handle();
}
// HandlerA is handling.
// HandlerB is handling.

public interface IHandler
{
    void Handle();
}

[Export(typeof(IHandler))]
public class HandlerA : IHandler
{
    public void Handle() => Console.WriteLine("HandlerA is handling.");
}

[Export(typeof(IHandler))]
public class HandlerB : IHandler
{
    public void Handle() => Console.WriteLine("HandlerB is handling.");
