When creating map with Spatial Reference SRID=3857 basemap is displayed correctly:
MyMapView.Map = new Map(new SpatialReference(3857));
MyMapView.Map.Basemap = Basemap.CreateStreets();
However, when I use different SRID for map, for example 2229 or 2230, the basemap is not displayed at all.
Am I doing something wrong?
What is the proper usage of basemap for maps with different SRIDs?
