Microsoft Feed Manager Events Example
I had trouble getting the GetWatcher method of the Feed Management API to work. Thanks to Matt Dotson's code on GotDotNet, I resolved the issue. The problem was a casting error; I was casting to FeedsWatcherClass instead of the IFeedEvents_Event interface. The corrected code now successfully attaches the watcher to the feed and handles FeedItemCountChanged and FeedDownloadCompleted events.
