I try to create a polylineZ shapefile with MapWinGis, in C# on VS2010.
Everything run but... why the shapefile contain everytime also the field M??
I've selected type POLYLINEZ for the shapefile and also for the shapes that I add, but the results are shapefileZM
The points are MapWinGis.Point with x, y and Z values set.
I could be try with dotspatial libraries but I think there are the same issue.

I don't want the M component because the file will be checked by a automatic process that don't accept M field.

Thank's so much.
