Hi Ben,
We have created a mobile application based on the ArcGIS Runtime for .NET. Currently we provide offline basemaps to the end user by creating a tile package (.tpk), and side loading this file onto the device. What we would like to do instead is create a tile package based on the ArcGIS Online World Street Map so we do not have to create the symbology ourselves at the different scale levels.
I thought that there might be tools in the latest version of ArcGIS for Desktop or ArcGIS Pro to create these tile packages, similar to the 'Create ArcGIS Runtime Content' tool or the 'Create Tile Package' tools that are both in ArcGIS for Desktop. Currently, it seems you cannot use those tools with ArcGIS Online content.
