Get type mapping names with NEST client

Is there a way to get the name of a type mapping using the GetMapping request in the NEST client? This was possible in Nest < 2.0, but does not seem to be possible in 2.0. For example, I would like to get the names of all the type mappings in an index using the following query:

nestClient.GetMappingAsync(m => m.Index(index).AllTypes());

This successfully returns a list of TypeMapping objects, but the actual names of the types is no where to be found.
