MapRouteFinder.GetDrivingRouteAsync and MapServiceToken in Windows Phone 8.1 XAML

Question

I have a Windows Phone 8.1 XAML app that uses the MapControl to display maps. In the MapControls Loaded event, I set a valid Bing API key

void MyMap_Loaded(object sender, RoutedEventArgs e)
{
    MyMap.MapServiceToken = the key
    MapService.ServiceToken = the key
}

I know the Bing API key is valid because the watermark in the MapControl is not shown.

From the page with the MapControl I navigate to another Page where in the ViewModel I try to find a driving route:

var driving = await MapRouteFinder.GetDrivingRouteAsync(new Geopoint(new BasicGeoposition
{
    Latitude = Latitude,
    Longitude = Longitude
}), Detail.GeneralInfo.GpsCoordinates.Position, MapRouteOptimization.Time);

The problem is that driving.Status is always InvaldiCredentials.

Is there something that I am missing?

The documentation says

Note that you have to provide the authentication token in two separate properties in an app that uses both Map services and the Map control.

and I did this.

The Bing API key I use is generated for Basic / Public Windows Phone App. I also tried to generate one for Basic / Public Windows App, no change.

No. I also tried to call `MapRouteFinder.GetDrivingRouteAsync` from the ViewModel for the page with the `MapControl`, same result. — Igor Kulman, Nov 20 '14 at 14:55
Does it work if you do the whole thing from code instead of a mix of XAML and code? — Steve Lillis, Nov 20 '14 at 14:56
No, still InvaldiCredentials when calling the code fragment from code behind of the page with the MapControl — Igor Kulman, Nov 20 '14 at 15:03
In my experience this sort of thing can be down to the difference between live and dev environments. Does this apply to you: https://social.msdn.microsoft.com/Forums/onedrive/en-US/c33be937-59a5-4b30-a9e7-cb2b870f6ed9/bing-map-control-invalid-credentials-when-connecting-to-staging?forum=vemapcontroldev. Other than that, I'm pretty much out of ideas :) — Steve Lillis, Nov 20 '14 at 15:05
Someone here (http://stackoverflow.com/questions/5283310/wp7-bing-maps-invalid-credentials-error) got the key again and applied it and it miraculously worked. Could be worth a shot. — Steve Lillis, Nov 20 '14 at 15:06

I have a working app that uses this token. I only set it to a Map control in XAML, and then I can use both the Map and the MapService, apparently.

My Maps key token is 22 characters long. The only way to get it is, AFAIK

Make an app
Upload it to the store but do not submit
You app gets associated with a store ID and you will see a map token
THAT is the token you will need

See screenshot. Is that the procedure you followed?

Also, make sure xmlns:Maps="using:Windows.UI.Xaml.Controls.Maps", not the old Bing control. Don't even know if the old control is still available in the Universal Apps btw

I had to manually edit the Package.appxmanifest file to make all the guids match and then it started to work, thanks! – Igor Kulman Nov 20 '14 at 21:31
That is odd. Usually the project/store menu option takes care of that. Make sure you don't re-use other apps' ids or you will run into funky problems when you submit. – LocalJoost Nov 28 '14 at 11:10
