Phone 8.0 Phone.Maps.Controls on Windows 10 Mobile RRS feed

  • Question

  • We have an application developed for Windows Phone 8 that is running on both Windows Phone 8 and Windows 10 Mobile devices. It has been a solid application without problems and we are in to process of porting it to a UWP.

    With the update to 10.0.15063.540, the app crashes when adding a MapPolyLine with no path to the map control.  (I understand the crash and have updated the app.)

    A second "feature" with this update is that the MapPolyLines no longer have the line thickness scaling with the zoom level of the map and setting the extents does not work correctly.  The extents are set and then an additional zoom in on the map occurs on the Windows 10 devices.

    Has anyone else noticed this behavior?


    The difference in the lines on a map is also seen when using the "hybrid" mode of the map when Microsoft's map lines are displayed on top of their aerial imagery.  On a Windows Phone 8 device, the line widths are appropriately scaled and do not overwhelm the map view.  On a Windows 10 Phone, the lines are overly thick and become overly dominant as a map feature instead of just enhancing the view.

  • Hi FMM_Salzburg

    I’m little confused about your problem.

    Is this issue appearing when you run the WP8 APP on Windows 10 Phone?

    Or is this issue appearing when you have ported it to a UWP app and is running the UWP app?

    Best regards,

  • The issue is running a WP8 App on a Windows 10 Phone.  (WP8.0 app, not an WP8.1 app)

    We are going to be creating a new build that targets Windows 10 UWP as well as Android devices.

    We also have a WP 7.5 app with the even older Maps control and the maps in that application was not affected by the latest Windows 10 update.
