NotSupportedExc occurs when placing a shapefile on a TileAsyncLayer

[TimThaler]

This exception occurs in ProjNet but i am posting it here since i might do something wrong with SharpMap. We have a shapefile which we want to use as an overlay for a standard -whole world showing - WMTS Webmercator TileAsyncLayer. The WKT representation of the Shapefiles CRS from its *prj reads like this:

GEOGCS["WGS 84", DATUM["World Geodetic System 1984", 
SPHEROID["WGS 84", 6378137.0, 298.257223563, AUTHORITY["EPSG","7030"]],
AUTHORITY["EPSG","6326"]], PRIMEM["Greenwich", 0.0, AUTHORITY["EPSG","8901"]], 
UNIT["degree", 0.017453292519943295], AXIS["Geodetic longitude", EAST], AXIS["Geodetic latitude", NORTH], AUTHORITY["EPSG","4326"]]

In SharpMap the two layers are used like this:

 MapBox.MapImageGeneratorFunction = MapBox.LayerListImageGenerator;
 var gss = new NtsGeometryServices();
 var css = new SharpMap.CoordinateSystems.CoordinateSystemServices(new CoordinateSystemFactory(), new CoordinateTransformationFactory(),  SharpMap.Converters.WellKnownText.SpatialReference.GetAllReferenceSystems());

 var pcs = (ProjectedCoordinateSystem)ProjectedCoordinateSystem.WebMercator;
 css.AddCoordinateSystem((int)pcs.AuthorityCode, pcs);
 GeoAPI.GeometryServiceProvider.Instance = gss;
 Session.Instance.SetGeometryServices(gss).SetCoordinateSystemServices(css).SetCoordinateSystemRepository(css);  

 Map map = new Map(){SRID = 3857};
 var tileSource =  new HttpTileSource(tileSchema: new GlobalSphericalMercator(0, 19, (string)null), urlFormatter: "https://{s}.tile.openstreetmap.org/{z}/{x}/{y}.png", serverNodes: new[] { "a", "b", "c" }, apiKey: null, name: null, persistentCache: null, tileFetcher: tileFetcher);
 var world = new TileAsyncLayer(tileSource, "world") { SRID = 3857, TargetSRID = 3857};
 string path ="C:\\Shapefile.shp";
 SolidBrush semiTransBrush = new SolidBrush(Color.FromArgb(128, 0, 0, 255));
 var vs = new VectorStyle { EnableOutline = true, Outline = new Pen(Color.Orange), Fill = semiTransBrush };
 FileInfo file = new FileInfo(path);

 string full = file.FullName;
 string name = Path.GetFileNameWithoutExtension(full);
 VectorLayer layer = new VectorLayer(name, new ShapeFile(full, true))
 {
       SRID = 4326,
       TargetSRID = 3857,
       Style = vs,
       SmoothingMode = SmoothingMode.AntiAlias
 };

map.Layers.Add(world);
map.Layers.Add(layer);
map.ZoomToBox(new Envelope(1492633.1458179, 1492733.1458179, 6894355.9492769623, 6894455.9492769623));

The part i really do not understand is that the following exception only occures after we build the final exe on a Jenkins Server. With a Debug or Release configuration in VisualStudio (Running with or without the Debugger) it works as intended!

The callstack of the exception:

System.NotSupportedException: No support for transforming between the two specified coordinate systems
   at ProjNet.CoordinateSystems.Transformations.CoordinateTransformationFactory.CreateFromCoordinateSystems(ICoordinateSystem sourceCS, ICoordinateSystem targetCS)
   at SharpMap.Layers.Layer.get_CoordinateTransformation()
   at SharpMap.Layers.VectorLayer.get_Envelope()
   at SharpMap.Forms.ImageGenerator.LayerListImageRenderer.Generate()
   at SharpMap.Map.MapViewChangedHandler.Invoke()
   at SharpMap.Map.set_Center(Coordinate value)
   at SharpMap.Forms.MapBox.OnMouseMove(MouseEventArgs e)

To track if maybbe one of the SRIDs got lost i added, not elegantly, some debuggingToFile to the Getter

 public virtual ICoordinateTransformation CoordinateTransformation
 {
     get
     {
         lock (lockobj)
         {
             using (var file = File.Open("C:\\Users\\tim\\Desktop\\output.txt", FileMode.OpenOrCreate))
             {
                 file.Seek(0, SeekOrigin.End);
                 using (var stream = new StreamWriter(file))
                     stream.WriteLine("TargetSRID: " + TargetSRID + " SRID: " + SRID);
             }
             if (_coordinateTransform == null && NeedsTransformation)
             {
                 var css = Session.Instance.CoordinateSystemServices;
                 _coordinateTransform = css.CreateTransformation(
                     css.GetCoordinateSystem(SRID), css.GetCoordinateSystem(TargetSRID));
             }
         }

         return _coordinateTransform;
     }
.....
}

There does not seem to be the problem as the output shows: TargetSRID: 3857 SRD: 4326. In the final installed directory i replaced every Dll from ProjNet to SharpMap.* to NTS ... But everytime the error occurs (only in the installation setup). Running it in VisualStudio it is very smooth and perfectly aligned. This i double checked with loading both layers in QGIS.

Why does this error occur and why only in the installation? Any help apprechiated!

The issue was that the method CreateFromCoordinateSystems in CoordinateTransformationFactory received null as the sourceCS parameter. We solved this by loading WGS84 in the CoordinateSystemServices.

 var gcs = GeographicCoordinateSystem.WGS84;
 css.AddCoordinateSystem((int)pcs2.AuthorityCode, gcs);

Why this exception only occured with the installation (e.g. the gsc is loaded/not loaded) remains a mystery though :)
