2.  Managed Extensibility Framework
 Open Source

3.  Makes extensible your Apps
 Speed-up!

4.  Think of the task
 Declare Export
 Declare Import
 Compose Both together

5.  [System.ComponentModel.Composition.ExportAttribute]
 [Export]
 public class Plugin1{...}
 [Export(typeof(Plugin2))]
 public class Plugin2 {...}
 [Export(“MitaTeknik.Plugin")]
 public class Plugin3 {...}
 [Export(typeof(IPlugin))]
 public class Plugin4: IPlugin{…}

6.  [System.ComponentModel.Composition.ImportAttribute]
 [Import]
 public Plugin1 Plugin {get ;set; }
 [Import(typeof(Plugin2))]
 public Plugin2 Plugin2 {get ;set; }}
 [Import(“MitaTeknik.Plugin")]
 public Plugin3 Plugin {get ;set; }
 [Import(typeof(IPlugin))]
 public IPlugin Plugin4 {get ;set; }

7.  [System.ComponentModel.Composition.Hosting.AssemblyCatalog]
 var catalog = new AssemblyCatalog(“Assembly”);
 var catalog = new DirectoryCatalog(“Extensions");
 var catalog = new AggregateCatalog(
new AssemblyCatalog(“Assembly”),
new DirectoryCatalog("Extensions"));
 var container = new CompositionContainer(catalog);
 var batch = new CompositionBatch();
batch.AddPart( this );
container.Compose(batch);
