I got a Utility Network asset package as a file geodatabase from Schneider Electric. This opens and behaves as expected in ArcGIS Pro. When I try to open several of the classes in ArcCatalog I get "Unable to instantiate class for XML schema type: ArrayOfFieldGroup".
Is there a problem with this FGDB, or are File Geodatabases not guaranteed to be sharable between Pro and ArcGIS 10x?
Thx,
Ed
