.NET Framework 4: Creating Extensible Applications with the Managed Extensibility Framework

In this 25-minute video, you'll learn about the Managed Extensibility Framework (MEF), a new library in the .NET Framework that enables greater reuse of applications and components. Using MEF, .NET applications can make the shift from being statically compiled to dynamically composed, helping developers write applications that are more extensible and easier to maintain than before.

Highlights:

  • 01:22 Moving from inheritence to composition.

  • 09:55 Export: using the Export attribute.
  • 10:18 Import: using the Import attribute.
