How to navigate between windows in WPF?

I have tried to set up a click event for a button that opens another window,but the error I'm getting at

NavigationService
is that the project doesn't contain a definition for it.

This is how I'm trying to call the page at present:

private void conditioningBtn_Click(object sender, RoutedEventArgs e)
{
this.NavigationService.Navigate(new Uri("TrainingFrm.xaml", UriKind.RelativeOrAbsolute));
}


Can someone point me in the right direction with this or show alternatives to this method for window navigation?

Answer

NavigationService is for browser navigation within WPF. What you are trying to do is change to a different window TrainingFrm.

To go to a different window, you should do this:

private void conditioningBtn_Click(object sender, RoutedEventArgs e)
{
    var newForm = new TrainingFrm(); //create your new form.
    newForm.Show(); //show the new form.
    this.Close(); //only if you want to close the current form.
}

If, on the other hand, you want your WPF application to behave like a browser, then you would need to create Pages instead of Forms, and then use a Frame in your application to do the navigation. See this example.
