Thomas, My apologies for not answering this earlier. I spent some time investigating this today. As currently implemented, the OpenRelationshipClass() method only works with feature service databases. We will review this implementation in a future release to see if we can extend it to cover additional database types. And we’ll definitely clarify the documentation as soon as possible. To open a relationship class with an SDE or file geodatabase, you need to use the Geodatabase.OpenDataset<RelationshipClass> method, passing in the name of the relationship class. If you don’t know the name of the relationship class you can find it and open it up using code like the following: IReadOnlyList<RelationshipClass> OpenRelationshipClass(Geodatabase geodatabase, string originClassName,    string destinationClassName) { List<RelationshipClass> relationshipClasses = new List<RelationshipClass>();  IReadOnlyList<RelationshipClassDefinition> relationshipClassDefinitions = geodatabase.GetDefinitions<RelationshipClassDefinition>(); foreach (RelationshipClassDefinition relationshipClassDefinition in relationshipClassDefinitions) {    if (relationshipClassDefinition.GetOriginClass() == originClassName && relationshipClassDefinition.GetDestinationClass() == destinationClassName)    {       relationshipClasses.Add(geodatabase.OpenDataset<RelationshipClass>(relationshipClassDefinition.GetName()));    }    relationshipClassDefinition.Dispose(); } return relationshipClasses; } I hope this helps, --Rich ...
