That looks promising, but does it use C#?

The demo utilizes several technologies including: IIS7, ASP.NET Ajax Extensions, Linq, Windows Communication Foundation, Windows Workflow Foundation, Windows Presentation Foundation, Windows Powershell, and the .NET Compact Framework. 

UPDATE: How do I get the line above that I copied/pasted to break?

>>Looking for a robust, maybe financial-based C# application to learn on. Creating "Hello World" and reordering my stamp collection apps are fine, but I also want something meaty that I can break/fix because that's a more real life situation. Found a couple online, but they just arent' complex enough. Many sample of functions, etc, but nothing full scale. Anyone know of something? Thanks!
