Related question: AutoMapper 11. Missing API replacements

Automapper v11 moved some functionality into “internal” apis (as pointed out in the upgrade guide)

however

When I downloaded the source code for v11.0.1, I found no references to “Advanced” except for in the upgrade guide

This is a bit unfortunate since I want to migrate from v10 and have “advanced” configurations, but no replacement for this api.

Am I missing something fundamental, or is this a bug in the guide/ missing migration step for a deprecated api?

Thanks
