I want to create basemap using my local tpk file in wpf app. How can i do it?

I've found some code for Map case:

Map myMap = new Map();

String filepath = "location_of_raster_file" ;

Raster myRasterFile = new Raster(filepath);

RasterLayer myRasterLayer = new RasterLayer(myRasterFile);
await myRasterLayer.LoadAsync();

myMap.Basemap.BaseLayers.Add(myRasterLayer);

But it doesn't work for Scene:

Scene newScene = new Scene();

String filepath = "C:\\Users\\user\\Desktop\\City.tpk";

Raster myRasterFile = new Raster(filepath);

RasterLayer myRasterLayer = new RasterLayer(myRasterFile);
await myRasterLayer.LoadAsync();

newScene.Basemap.BaseLayers.Add(myRasterLayer);

Hi Vanya Ivanov,‌

To use a TPK, do not use a RasterLayer. Instead use an ArcGISTiledLayer with a TileCache initialized with the TPK.

See the example here: ArcGISTiledLayer Constructor (TileCache)

Hope this helps.

var tileCache = new TileCache(Constants.Settings.ImageryLocation);
ArcGISTiledLayer imageLayer = new ArcGISTiledLayer(tileCache);

var map = new Esri.ArcGISRuntime.Mapping.Map(new Basemap(imageLayer))
{
	InitialViewpoint = new Viewpoint(extent)
};‍‍‍‍‍‍‍‍‍‍‍‍‍‍

You can also with :

private const string MAP = "map.tpk";
 .... 
..... 
Uri uri = new Uri(MAP); 
// Create a tile cache from the local data. 
TileCache cache = new TileCache(uri.LocalPath); 
// Use the tile cache to create an ArcGISTiledLayer. 
ArcGISTiledLayer tiledLayer = new ArcGISTiledLayer(cache); 
// Display the tiled layer as a basemap. 
MyMapView.Map = new Map(new Basemap(tiledLayer));
