Windows Phone 7.1 GPS

Question

I am trying to use a string that has a location(ie a book store read from an xml file) and then gives you directions from your current location to reach that particular book store. I am unsure as to how to do this. I believe it requires bing maps, but I am wondering if anyone has any code that performs a similar operation. Maybe you need specific coordinate points to be read in from the XML file? Thank you for your time and help!

You can rely on BingMapsDirectionsTask to accomplish that easily. Following is an example on how to show direction from current location to a book store location :

var directionTask = new BingMapsDirectionsTask();
var bookStoreCoordinate = new GeoCoordinate(Double.Parse(latitudeStringFromXml, CultureInfo.InvariantCulture),
                                            Double.Parse(longitudeStringFromXml, CultureInfo.InvariantCulture)));
directionTask.End = new LabeledMapLocation("book store name", bookStoreCoordinate);
directionTask.Show();
