WHAT'S IN THIS CHAPTER?

Understanding the Location API
How to look up your current location with the GeoCoordinateWatcher class
How to use the CivicAddressResolver class

Windows Phone 7 offers a Location API that allows you to determine your location in multiple ways, including GPS, WiFi lookup, and cell tower triangulation. This chapter prepares you for using that service.

UNDERSTANDING AND ACCESSING THE LOCATION API

The Location API is provided so that you don't have to worry about customizing your game or application for specific hardware configurations. This includes not needing to worry about the specifics of how the data is acquired (via GPS, cell tower, and so on).

Everything you need to access your phone's location is stored within the System.Device .Location namespace. You will be concerned with three types of data in this chapter: CivicAddress, GeoCoordinate, and GeoPosition.

BEST PRACTICES FOR USING LOCATION SERVICES

In this chapter, you will learn several different ways to interact with the Location API inside your game or app. What follows are some best practices when dealing with location data.
