In ArcGIS Maps SDK for .NET in a .NET MAUI app, labels for polylines display upside down when rotating the map

Solution de contournement

Calculate the centroid of the polyline and label the point graphics instead of the polyline using the methods below:

public MapPoint GetPolylineCenterPoint(Polyline polyline)

{

  // Ensure the polyline has points

  if (polyline.Parts.Count == 0 || polyline.Parts.First().Points.Count == 0)

  {

    return null;

  }

  // Flatten all points in the polyline

  var allPoints = polyline.Parts.SelectMany(part => part.Points).ToList();

  // Calculate the average of the X and Y coordinates

  double avgX = allPoints.Average(point => point.X);

  double avgY = allPoints.Average(point => point.Y);

  // Create and return the center point

  return new MapPoint(avgX, avgY, polyline.SpatialReference);

}
