Basic Calculator

A simple calculator for WPF
Here is a calculator application for Windows Presentation Foundation created with Expression Interactive Designer and Visual C# Express Edition. To use this on WindowsXP you need some stuff from this Get The Beta page.
The calculator has only the most standard functions. But I tried to make it easily extensible; I hope to make more useful calculators also.
Larger View

Nested grids allow different areas to stretch in different ways.
I had a lot of fun making this, even though it took longer than I expected and the migration from January to February CTPs stalled me a bit. Much of the logic is based on the AvalonCalculator2 sample from the Windows SDK. There are also many C# calculator samples online, but this Resizable Calculator using C# was particularly inspiring and I feel offers a neat comparasin in what "resizable" means in WPF versus non-WPF.
