在WindowsPhone中需要调用系统资源的话需要用到启动器（Launcher）和选择器（Choosers）。

BingMapsDirectionsTask bingMapsDirectionsTask = new BingMapsDirectionsTask();            
GeoCoordinate spaceNeedleLocation = new GeoCoordinate(0,0);
LabeledMapLocation spaceNeedleLML1 = new LabeledMapLocation("Somewhere", spaceNeedleLocation);
LabeledMapLocation spaceNeedleLML2 = new LabeledMapLocation("qingdao", null);
bingMapsDirectionsTask.End = spaceNeedleLML2;
bingMapsDirectionsTask.Start = spaceNeedleLML1;
bingMapsDirectionsTask.Show();

其中LabeledMapLocation的第二个参数为地理坐标，如果为NULL的话，bing地图会根据第一个参数的字符串进行搜索

另外如果不设置bingMapsDirectionsTask.Start的话，默认以当前GPS定位为出发地址。

效果：

最后，bing map在米国貌似不错，天朝比较坑爹…路径导航基本没戏….

还有手机区域语言选中国，基本不工作，选英国、米国都正常…
