New Post: Exception UpdateEnvelope in type NetTopologySuite.Geometries.LineString does not have implementation

DotSpatial.NetTopologySuite version 1.14.4.0

InnerException
"Method 'UpdateEnvelope' in type 'NetTopologySuite.Geometries.LineString'
from assembly 'DotSpatial.NetTopologySuite, Version=1.14.4.0, Culture=neutral, PublicKeyToken=f580a05016ebada1'
does not have an implementation.":
"NetTopologySuite.Geometries.LineString"} System.Exception {System.TypeLoadException}
There are only to elements load at the start of the application:

private DotSpatial.Positioning.Forms.Compass Compass;
private DotSpatial.Symbology.Forms.AngleControl acHeading;

I could really use some help understanding this.
