What is a good open source .NET application to learn from?

Question

I'm looking for a small- to medium-sized, open-source .NET application to learn from and model my own development after.

Key features:

• Good project organization
• Unit testing
• Design patterns
• Follows good OO design principles
• Clear, human-readable code

VB.NET is preferred, but C# also appreciated.

Thanks!

if you are looking for some guidelines for a web based biz application, consider the following: http://code.google.com/p/sharp-architecture/

It has some good coverage on a few topics you're interested (proj organization, unit testing, patterns). The latest version added scaffolding for code generation. It's in C#.

Take a look at NUnit, too. While I haven't looked closely at their code, I seem to remember it looking OK.
