[Solved] LegacyConnectionAny and GetAllConnectionsControlPoints();

[Trainzland]

Solved: Used a different approach.

Code:

public override void OnClick() {
           var selectedCP = DTSelection.GetAs<CurvySplineSegment>();
           var cps = new List<CurvySplineSegment>();
           var connection = selectedCP.Connection;
           cps.Add(selectedCP);
           if (connection != null) {
               foreach (var ccp in connection.ControlPoints) {
                   if (!cps.Contains(ccp)) {
                       cps.Add(ccp);
                   }
               }
           }
