    Syntax
    Example
    Get the attribute rotation field of a layer
    var featureLayer = MapView.Active.Map.GetLayersAsFlattenedList().OfType<FeatureLayer>().FirstOrDefault();
    QueuedTask.Run(() =>
    {
      var cimRenderer = featureLayer.GetRenderer() as CIMUniqueValueRenderer;
      var cimRotationVariable = cimRenderer.VisualVariables.OfType<CIMRotationVisualVariable>().FirstOrDefault();
      var rotationInfoZ = cimRotationVariable.VisualVariableInfoZ;
      var rotationExpression = rotationInfoZ.ValueExpressionInfo.Expression; // this expression stores the field name  
    });
    Find connected attribute field for rotation
    var featureLayer = MapView.Active.Map.GetLayersAsFlattenedList().OfType<FeatureLayer>().FirstOrDefault();
    ArcGIS.Desktop.Framework.Threading.Tasks.QueuedTask.Run(() =>
    {
      // get the CIM renderer from the layer
      var cimRenderer = featureLayer.GetRenderer() as ArcGIS.Core.CIM.CIMSimpleRenderer;
      // get the collection of connected attributes for rotation
      var cimRotationVariable = cimRenderer.VisualVariables.OfType<ArcGIS.Core.CIM.CIMRotationVisualVariable>().FirstOrDefault();
      // the z direction is describing the heading rotation
      var rotationInfoZ = cimRotationVariable.VisualVariableInfoZ;
      var rotationExpression = rotationInfoZ.Expression; // this expression stores the field name  
    });
