[UWP] Map is not showing in Release

[marshallcoco]

VERSIONS

• Xamarin.Forms.GoogleMaps - 3.3.0
• Xamarin.Forms - 4.5.0

PLATFORMS

• [ ] Android
• [ ] iOS
• [x] UWP

ACTUAL BEHAVIOR

I work on a Xamarin.Forms application targeting UWP, which uses Xamarin.Forms.GoogleMaps. In Debug, everything works fine but in Release the map doesn't show up (it's completely blank).

HOW TO REPRODUCE

I generated a Bing Map API key (MY_KEY in code below) with this properties:

• Key type = Basic
• Application type = Windows Application I have a doubt regarding Application name but whatever I tried to put there, the map worked in debug and didn't work in release.

In UWP project, App.Xaml.cs, OnLaunched method I put this code:

           var rendererAssemblies = new[]
            {
                typeof(Xamarin.Forms.GoogleMaps.UWP.MapRenderer).GetType().Assembly
            };

            Xamarin.FormsGoogleMaps.Init("MY_KEY");

            Xamarin.Forms.Forms.Init(e, rendererAssemblies);

And of course there is a view with a map in my application: xmlns:maps="clr-namespace:Xamarin.Forms.GoogleMaps;assembly=Xamarin.Forms.GoogleMaps"

As mentioned above, this works fine in Debug mode (map is displayed, centered on Rome) but in Release the map is blank.

Thanks!

Any updates on this issue? This issue is still present.

Looks like if you are compiling with the .NET Native toolchain you need to set the rendererAssemblies in App.xaml.cs to point to the UWP renderer, and not the portable renderer
