That's really harsh... Alright, You haven't mentioned this, but I suppose, that you try to solve the problem of navigating from UserControl to other page/uc(is it true?).

A couple of edits:

  1. First, You don't need an object of class to use a NavigationSevice.
  2. Second, the NavigationService is most usually used with pages.

If you really do want to use it with UserControl, you should transfer an instance of page to control. But, in my experience, usually, this is not required. I would rather recommend to do in this way:

In your UserControl you will most definitely have the controls with tap/click events. No need to describe their logic in user control class. When you add the user control to page, you should declare it there. Like:

someUserControl.buttonNavigate.MouseLeftButtonUp += new MouseButtonEventHandler(buttonNavigate_Click);

And then you can use navigation service.

NavigationService.Navigate(new Uri(...));

That's the easiest solution. Hope it helps.

There are another ones, but I hope this one will solve the problem.
