MapView

---

A map view lets you display geographical data within your app and supports most of the functionality provided by the built-in Maps app. A map view can be configured to show a standard map, satellite imagery, or both. It can include pins and overlays, and supports zooming and panning. If your app supports routing, such as in a run-tracking app, you can use a map view to display the route.

Best practices

• In general, keep your map interactive. People are accustomed to using gestures to interact with the Maps app, and expect to be able to interact with your map in similar ways.
• Use expected pin colors. A pin identifies a point of interest on your map. People are familiar with the standard pin colors in the Maps app. Avoid redefining the meaning of these colors in your app. Use red for a destination, green for a starting location, and purple for a user-specified location.

How to use

1. Drop a MapView control from the object panel to a Window
