Map Mobile package basemap in uwp app

Question

Hi, I am new to ArcGIS development. I am trying to open map mobile package mmpk in uwp .net application. I have loaded the package in the map and I can see all the layers. Basemap is not part of mmpk package. I am unable to figure out how to display basemap with mmpk in UWP app. Can you help?

I tried the code. It's working perfectly. Thank you so much.

Thanks for sharing your MMPK. That helped. Your map has a spatial reference of WGS 84. Your solution is to do this: * Go to this page and pick a WGS84 basemap. * On the Basemap's item page, pick out the GUID from the URL (e.g. 02b1f120c3674bfe896ac81731be1739 for https://www.arcgis.com/home/item.html?id=02b1f120c3674bfe896ac81731be1739 ) * Create a Basemap from a Portal Item using that ID with code like this, setting it on the map from the MMPK, then setting the map on the map view:try { MobileMapPackage myMapPackage = await MobileMapPackage.OpenAsync(""); if (myMapPackage.LoadStatus != LoadStatus.Loaded && myMapPackage.LoadError != null) { //TODO } ArcGISPortal arcGISPortal = await ArcGISPortal.CreateAsync(); PortalItem portalItem = await PortalItem.CreateAsync(arcGISPortal, "02b1f120c3674bfe896ac81731be1739"); Basemap basemap = new Basemap(portalItem); Map map = myMapPackage.Maps.First(); map.LoadStatusChanged += Map_LoadStatusChanged; map.Basemap = basemap; MyMapView.Map = map; } catch (Exception) { throw; }‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍ Our default basemaps that you create from our Basemap factory methods are spatial reference Web Mercator. The map that is obtained from the MMPK already has its spatial reference set (which I did not expect, but it turns out that's the case with maps from an MMPK). Hope this helps (thanks Michael Branscomb‌ for the .NET code!)

Thanks for the response. As you mentioned I tried codes below. I am still unable to view basemap.

1. StorageFolder folder = await ApplicationData.Current.LocalFolder.GetFolderAsync("Pole");

StorageFile f = await folder.GetFileAsync("mmm.mmpk");

MobileMapPackage myMapPackage = await MobileMapPackage.OpenAsync(f.Path);

Basemap b = Basemap.CreateImageryWithLabels();

myMapPackage.Maps.First().Basemap = b;

MyMapView.Map = myMapPackage.Maps.First();

2.   StorageFolder folder = await ApplicationData.Current.LocalFolder.GetFolderAsync("Pole");

StorageFile f = await folder.GetFileAsync("mmm.mmpk");

MobileMapPackage myMapPackage = await MobileMapPackage.OpenAsync(f.Path);

Basemap b = Basemap.CreateStreetsVector();

MyMapView.Map = myMapPackage.Maps.First();

MyMapView.Map.Basemap = b;
