Is there an equivalent to ArcObjects IJunctionFeature or IEdgeFeature?

Discussion created by MMcCall on Feb 4, 2014
In ArcObjects using Engine it is simple to access basic directly connected feature information by casting an IRow instance to IJunctionFeature or IEdgeFeature.  I can't find any equivalents in the Runtime API. 

It looks to me like it may be possible to use Geoprocessing Tasks, but this would require a higher level of client licensing than what we currently require and would seem to be overkill compared to what is very simply done in ArcObjects.

Is there any equivalent in Runtime API I may have missed?  If not, will these interfaces (or similar) be included in Runtime for .Net?

Thank You
