Points Fail to Appear

I'm looking at the WPF example and noticed that the points you've added appear in the designer but not at run time. I'm having a similar issue with my application, any idea why this is occurring?

Example XAML in question (MainWindow.xaml in WpfApplication) -
<map:MapItemsControl ItemsSource="{Binding Points}"
                                 ItemContainerStyle="{StaticResource PointItemStyle}"
Points is just an ObservableCollection, so as far as I understand it they should be appearing. But the only one that shows up is the last one, which is the animated point.

EDIT: Actually I found the issue with the example -

In MapBase.cs you originally had:
ViewportChanged?.Invoke(this, EventArgs.Empty);
Which did not compile. I had originally just tried commenting it out, but replacing it with this fixed the issue:
if (ViewportChanged != null)
    ViewportChanged.Invoke(this, EventArgs.Empty);

?. is the null-conditional operator.

You should probably upgrade to Visual Studio 2015.
