Download street map and Imagery for offline use

[JasonTrinidad1]

Hello. I'm new to ArcGis, and wanted to know if there's a way to download World Imagery and/or street maps for offline use in ArcGis runtime for.NET. I read that I need a .geodatabase, so I downloaded ArcMap. I followed this link

Creating ArcGIS Runtime content—Help | ArcGIS for Desktop

1. I go to ArcMap
2. Create new blank map
3. Right click Layers, and add New Basemap Layer
4. Click File -> ArcGIS Online...
5. Add a map
   1. Tried World Imagery (for Export), OpenStreetMap WorldStreetMap
6. When I try to Share as ArcGIS Runtim Content I get a Code 00005 "Layer type is no supported"

I also tried downloading the .lyr, .lpk, and .mxd for these maps online, but nothing has worked.

I only need to get an offline Street and/or Imagery map for development. Any help is appreciated. Thanks.
