WPF performance and .NET Framework Client Profile related blogs provided by Jossef Goldberg.
made some small bug fixes to my WPF Calculator sample app (that is/was already included in the .Net 3.0 SDK) and I also added the startup Splash Screen from my earlier blog .
For my personal use, I find this app to be much more useful than the Calculator accessory that is shipped with Windows. I use it almost on a daily basis.
I really like the "paper trail" feature as it allows me to see the operations that I entered and check for errors. I also like the fact that I can see what is the value stored in the 'Memory'.

You can install the app from here.
Since SkyDrive and msdn do not support ClickOnce apps the installer is currently using MSI.
