.NET Framework Managed Extensibility Framework Exporting a Type (Basic)
Example
using System.Collections.Generic;
using System.Collections.ObjectModel;
using System.ComponentModel.Composition;
namespace Demo
{
[Export(typeof(IUserProvider))]
public sealed class UserProvider : IUserProvider
{
public ReadOnlyCollection<User> GetAllUsers()
{
return new List<User>
{
new User(0, "admin"),
new User(1, "Dennis"),
new User(2, "Samantha"),
}.AsReadOnly();
}
}
}
This could be defined virtually anywhere; all that matters is that the application knows where to look for it (via the ComposablePartCatalogs it creates).
