.NET Framework Managed Extensibility Framework
Remarks
One of MEF's big advantages over other technologies that support the inversion-of-control pattern is that it supports resolving dependencies that are not known at design-time, without needing much (if any) configuration.
All examples require a reference to the System.ComponentModel.Composition assembly.
Also, all the (Basic) examples use these as their sample business objects:
using System.Collections.ObjectModel;
namespace Demo
{
public sealed class User
{
public User(int id, string name)
{
this.Id = id;
this.Name = name;
}
public int Id { get; }
public string Name { get; }
public override string ToString() => $"User[Id: {this.Id}, Name={this.Name}]";
}
public interface IUserProvider
{
ReadOnlyCollection<User> GetAllUsers();
}
}
