Omar forwarded me a link to his RSS Feeder .NET sample on CodeProject - it's a fantastic example of a Windows Forms smart client app that takes advantage of many of the application blocks from the Enterprise Library, and demonstrates Outlook integration, offline caching, asynchronous communication, and multi-threaded application logic updating UI. Omar has generously made it available under the BSD license, so you can take it to pieces, analyze it, and even incorporate pieces of it within your own code.
It's work like this that gets you noticed in the developer community. Omar also has a really innovative personal website that shows his talents off very effectively. As someone who hasn't yet graduated from university, Omar looks like he's got a great future ahead of him.
