Dare Obasanjo has published sample C# code and an EXE at the Microsoft Developer Network (MSDN) for an RSS news aggregator. To my surprise, it does some interesting things like importing OPML subscription lists. It also seems to handle both RSS 0.91 and RSS 2.0 feeds, and has some neat tricks like browsing directly in the aggregator (why not if you’re embedding IE?).
NetNewsWire it isn’t. In fact, it’s not quite up to Radio’s standards either. There are some definite GUI issues, like not remembering the width of columns and not being able to resize any of the panes in the main window; no delete confirmation for subscriptions; no memory of read items between updates; and calling the “mark all as read” option “Catch Up” (logical, but I was expecting something consistent with all the other email, news, and RSS apps I’ve seen). But it is free, and for all you C# hackers out there it gives good sample code.
Now if only MSDN would add an RSS feed…
