Demo mode: unhandled exception on step 3 - pick a place

[jpj-verstappen]

I took the latest version from GitHub, with last commit on April 20th, 2019. I got things to compile on Visual Studio 2017, and Windows 10 version 1803.
When running the app, selecting the colleagues works, choosing a date and time works, and then when I press 'Next' I get an unhandled exception:

◢ | Exception | {System.Runtime.InteropServices.SEHException (0x80004005): External component has thrown an exception. at Windows.UI.Xaml.Controls.Maps.MapControl.put_MapServiceToken(String value) at LunchScheduler.Views.PlacesPage.XamlBindingSetters.Set_Windows_UI_Xaml_Controls_Maps_MapControl_MapServiceToken(MapControl obj, String value, String targetNullValue) at LunchScheduler.Views.PlacesPage.PlacesPage_obj1_Bindings.Update_LunchScheduler_Models_Constants_MapServiceToken(String obj, Int32 phase) at LunchScheduler.Views.PlacesPage.PlacesPage_obj1_Bindings.Update_(PlacesPage obj, Int32 phase) at LunchScheduler.Views.PlacesPage.PlacesPage_obj1_Bindings.Update() at LunchScheduler.Views.PlacesPage.PlacesPage_obj1_Bindings.Initialize() at LunchScheduler.Views.PlacesPage.PlacesPage_obj1_Bindings.Loading(FrameworkElement src, Object data)} | System.Exception {System.Runtime.InteropServices.SEHException}

I haven't been able to figure out what goes wrong here. I only suspect getting/displaying a map is the issue.
