Part 6 of a series of screencasts looking at the new Managed Extensibility Framework (MEF) in the Silverlight 4 beta.
MEF is a framework that simplifies the design of extensible applications and components. It can flexibly and dynamically discover a set of loosely coupled components and analyse their dependencies in order to compose them together at run time.
In this screencast we take a look at how we can provide defaults in a CompositionContainer such that an application can be sure that it has an implementation of a plug-in if no additional plug-in is discovered by MEF. This leads to a discussion about
ExportProviders and how they provide an extensibility point for MEF.
Tips for viewing:
- Each video in this series has a 3.5 minute standard introductory "header" on it so once you have seen that header you may like to skip it on subsequent videos
- For the time pressured - I find that I speak so slowly that you can speed me up to approximately 1.5-2.0 times normal speed and still listen comfortably.
I'm working to get together a Live Meeting in early 2010 with people from the MEF team in order that people can chat more about MEF in Silverlight. Stay tuned.
