ArcGIS Pro version: 2.5


I have created a filegeodatabase with 2 Feature Classes and 1 Relationship Class with a Table (AttributedRelationshipClass). 

The AttributedRelationshipClass defines the link between those two featurelayers using GUIDs and a few properties for the relation. 


I used the ArcGis Pro sdk (c#) to add the feature classes to the map: 

var map = Project.Current.GetItems<MapProjectItem>().FirstOrDefault(e => e.Name == name);

var lyrDocFromLyrxFile = new LayerDocument(layerFile);
var cimLyrDoc = lyrDocFromLyrxFile.GetCIMLayerDocument();
var lcp = new LayerCreationParams(cimLyrDoc);
LayerFactory.Instance.CreateLayer<FeatureLayer>(lcp, map, LayerPosition.AutoArrange);


I tried to add the table with: 


using (var table = geodatabase.OpenDataset<Table>(relationshipName))
StandaloneTableFactory.Instance.CreateStandaloneTable(table, map, table.GetName());

The datatype is then: esriDatasetType.esriDTTable.

This resulted in these warnings: 



When I right click on the warning I get the option to add the table to the map. Then the table is added in the correct way with the datatype: esriDatasetType.esriDTRelationshipClass. 


Is it possible to do this with the ArcGIS Pro .NET sdk?
