Something like this var overlay = MyMapView.GraphicsOverlays["areaOfInterestOverlay"]; if (overlay.Graphics.Count == 0) return; var basemap = MyMapView.Map.Basemap.BaseLayers.OfType<ArcGISTiledLayer>().First(); var lods = basemap.ServiceInfo.TileInfo.LevelsOfDetail; ExportTileCacheTask estimateTilesTask = null; ExportTileCacheJob job = null; try { estimateTilesTask = await ExportTileCacheTask.CreateAsync(basemap.Source, Authenticat ionManager.Current.Credentials.FirstOrDefault()); var parameters = await estimateTilesTask.CreateDefaultExportTileCacheParametersAsync( overlay.Graphics.First().Geometry.Extent, lods[0].Scale, lods[10].Scale); job = estimateTilesTask.ExportTileCache(parameters, @"yourpathtothetpk.tpk"); var result = await job.GetResultAsync(); //await result.LoadAsync(); // Do something with loaded tile cache } catch (Exception ex) { Debug.WriteLine(ex.ToString()); } foreach (var joMessage in job.Messages) { Debug.WriteLine(joMessage.Message); } ‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍
