继续进入 vnext 的旅程...
我现在可以构建整个解决方案并成功运行它。但是，当我尝试初始化 IMvxGeoLocationWatcher 时，它会崩溃。代码和输出是 -
private IMvxGeoLocationWatcher _geoWatcher;
public void StartGettingLocation(Action<MvxCoordinates> response)
{
Log.Info("LocationService->StartGettingLocation");
// crashes on this line -
if (_geoWatcher == null) _geoWatcher = this.GetService<IMvxGeoLocationWatcher>();
输出 -
