Basemap does not display for some SpatialReference (SRID)

[WaldemarNowak]

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?

Tiled layers does not support auto-reprojection so you would need to use layers in your basemap that has the correct prijextiop, or use a layer type or service that supports projecting to the spatial reference you need.
