Clearly, WPF does support touch screens.
Please provide more information on how it's not working and/or what you want to accomplish.

the same application works different if I use mouse for button with event PreviewMouseDown or use my finger on that button.
With mouse the auction I expect just happens with finger first some square appears on button before something happens. The action using mouse takes 1 sec using touch screen 3 sec. For my application this is critical .
