v4.0 migration - LinesString - how to add track to map ?

HI,

looking if v4.0 may solve issue with track I am trying to migrate my code to it. But I am having issue how to do it with line string. currently I am creating line string this way:

List<MPoint> segmentPoints = new List<MPoint>();
foreach (XmlElement xelement in xmlPoints) //fetching points from XML file
{
   segmentPoints.Add(SphericalMercator.FromLonLat(Convert.ToDouble(xelement.GetAttribute("lon")), Convert.ToDouble(xelement.GetAttribute("lat"))).ToMPoint());
 }

var feature = new GeometryFeature() // creating feature layer
{
  Geometry = new LineString(segmentPoints.ToArray())  // this is where I need help, how do I construct linestring from MPoints list ?
};

This issue is caused by same error as #1514 (number format conversion from non US to US) You can close this

One more thing. MPoint is part of Mapsui itself (along with MRect and MQuad), while LineString is part of NTS. If you work with NTS it makes more sense to work with NTSs Point or Coordinate. There are extension methods for converting between them.

And I see we even have an MPoint ToCoordinate extension method. Perhaps we should also add an ToCoordinates that takes an IEnumerable<MPoint>
