Introduction
One of the most powerful features of smartphones today is location awareness. Windows Phone 7 is no exception. The wide consumerization of GPS around 10 years ago brought handheld GPS receivers for consumers on the go, but few individuals could justify the expense or pocket space. Now that smartphones have GPS built in, developers have built incredibly powerful applications that are location-aware. For example, apps that help users track their jogging route, get real-time navigation assistance while driving, and map/analyze their golf game.
In this chapter, we will take a deep dive into the location API for Windows Phone 7 by building an application to help navigate during travel and another to map the user's location.
