Hello,

In order to achieve controls which can be easily operated in touch environment we have created two touch-friendly Metro themes - one light (Metro theme) and one dark (Metro Dark theme). For more information on using these themes you may refer to the following topic:

The easiest way to apply such a theme and achieve a touch-friendly application is applying the theme on application level. This can be done by the means of the ThemeManager component with a single line of code similar to:

ThemeManager.ApplicationTheme = new MetroTheme();

For detailed information on the ThemeManager component I suggest referring to the following set of help topics:

Let me know if I can provide any further assistance.
