title: DateTimePicker for WPF 4.0
body: <p>According to <a href="https://stackoverflow.com/questions/560811/how-to-use-datetimepicker-in-wpf">this post</a>, there's a separate DatePicker control in .net 4. I've tried it, and I don't see a good way to also let it select the time of the day.</p>
  
  <p>Is there an easy way to transform DatePicker into DateTimePicker by editing XAML template? If not, what is the best way to get a DateTimePicker for WPF 4.0?</p>
