About

Provides the Managed Extensibility Framework (MEF) 2.0, a lightweight, attribute-driven Dependency Injection (DI) container.

MEF simplifies the composition of applications by allowing components to be loosely coupled and dynamically discovered. This package supports the development of modular and maintainable applications by enabling parts to be composed at runtime.

Key Features

  • Components are discovered and composed using attributes.
  • Provides dependency injection capabilities for loosely coupled modules.

How to Use

Running code from a discovered component.

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

var configuration = new ContainerConfiguration().WithPart<Service>();

using var container = configuration.CreateContainer();

var service = container.GetExport<Service>();
service.Execute();
// Output: Service is running!

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

Main Types

The main types provided by this library are:

  • System.Composition.ExportAttribute
  • System.Composition.ImportAttribute
  • System.Composition.Convention.ConventionBuilder
  • System.Composition.Hosting.CompositionHost
  • System.Composition.CompositionContext
