I've written a simple game-like app in WPF. The number of objects drawn is well within WPF capabilities - something like a few hundred ellipses and lines with simple fills. I have a DispatcherTimer to adjust the positions of the objects from time to time (1/60th of a second). The code to compute the new positions can be quite intensive ...
We have an application that needs the 3.5 SP1 framework and when we click on the prerequisite option in the setup kit we made, we only see the framework without the SP1.

So, m...

I've got a plain-old WPF ListBox defined in my .xaml: ... <ListBox Name="foo"> </ListBox> ... In my matching .xaml.cs I programmatically add strings to this ListBox.
