What are some good beginner programmes I could write to practice?

My very first application with C# was an RSS reader. It wasn't that hard, and at that moment I only had experience with PHP and some noobish scripting-ish programming language (GML), so I think it fits for beginners. I used a good tutorial for this, it's an official one of MSDN:

http://msdn.microsoft.com/vstudio/express/beginner/windows/tier3/beginA/cs/

It learns the basics of C#, and how you can parse XML files. You'll also use a local SQL database to store the channels and such, so it covers alot.

It didn't take me that long, and after that I think I didn't really had to view many more tutorials because I had enough knowledge of C# to do it all by myself.
