IronRuby is probably not a catchy term or topic, as there were only ten or so attendees...including me and the guy that was raising banners at the back bearing the words "15 minutes" and "5 minutes." That just shows how much harder we need to work in order to increase awareness of the topic in the Singapore .NET community. In any case, it was gratifying to see the collective amazement of those that were present when they saw the dynamic features of the Ruby language, and even more when they saw the DLR console for Silverlight, which allows the user to inspect and even modify the appearance and behaviour of a live, running Silverlight web app. Can C# or VB.NET do that?

Thanks to the IronRuby guys for coming up with the IronRuby 0.5.0 release just a few days before the presentation. Jimmy Schementi was also very helpful in pointing me towards how to call Ruby objects from within C#.
