My two-part article on rebuilding an existing Silverlight application to use MEF (Managed Extensibility Framework) for “selective composition” is now live on SilverlightShow.net (part 1, part 2). I took my Halloween Gallery application and made it pluggable so I can pull in different themes throughout the whole year (current themes include Halloween and Christmas).

The original features are still there – geotagged photos are retrieved from Flickr API and the location where they were shot is shown on the Bing Map. If you’re interested in MEF, take a look at let me know what you think. The application will be released to Codeplex soon.
