Edit Operation Planarize Features
// note - EditOperation.Planarize requires a standard license. 
//  An exception will be thrown if Pro is running under a basic license. 

var planarizeFeatures = new EditOperation() { Name = "Planarize Features" };

//Planarize one or more features
planarizeFeatures.Planarize(featureLayer, new List<long>() { oid });

//Execute to execute the operation
//Must be called within QueuedTask.Run
if (!planarizeFeatures.IsEmpty)
{
  var result = planarizeFeatures.Execute(); //Execute and ExecuteAsync will return true if the operation was successful and false if not
}

//or use async flavor
//await planarizeFeatures.ExecuteAsync();
