It's all about enhanced Ux (User eXperience). VFP, WinForms, pretty much any business app uses GDI or GDI+ to render objects. GDI dates back to Win 3.11 or even earlier. Microsoft felt it was time for an update, hence WPF. It's basically wrappers around DirectX. Now DirectX is pretty complicated stuff and hard to use directly. It's really only used that way for games. Now it's easy.

With WPF, you don't specify row, column for control placement. Instead you lay out a grid and put controls in the grid cells (similar to how you do layout in HTML.) Things then resize automatically and still look good. You can also do fancy stuff like have a different running video for each item in a listbox (not that you'd do that, but you could).
