@Maddogtet , thank you for this contribution and signing the CLA.
Do you mind rebasing you PR on current development branch so we can see the CI working? That would be great.

Is this common? Where do you get the WKT from?

@FObermaier looks like this is a problem with the current release from the master branch
Creating a coordinate system from correct wkt with the current release, leads to this broken wkt if you read it again from the coordinate system.

            string wkt = "PROJCS[\"DHDN_3_Degree_Gauss_Zone_4\",GEOGCS[\"GCS_Deutsches_Hauptdreiecksnetz\",DATUM[\"D_Deutsches_Hauptdreiecksnetz\",SPHEROID[\"Bessel_1841\",6377397.155,299.15281280],TOWGS84[598.1000,73.7000,418.2000,-0.202000,-0.045000,2.455000,6.70000000]],PRIMEM[\"Greenwich\",0],UNIT[\"Degree\",0.017453292519943295]],PROJECTION[\"Transverse_Mercator\"],PARAMETER[\"False_Easting\",4500000.000],PARAMETER[\"False_Northing\",0.000],PARAMETER[\"Scale_Factor\",1.000000000000],PARAMETER[\"Central_Meridian\",12.00000000000000],PARAMETER[\"Latitude_Of_Origin\",0.00000000000000],UNIT[\"Meter\",1.00000000000000]]";
            var coordinateSystemFactory = new CoordinateSystemFactory();
            var coord = coordinateSystemFactory.CreateFromWkt(wkt);
            Assert.NotNull(coord);
            Assert.AreEqual(wkt, coord.WKT);

I was not able the reproduce the creation of that broken wkt with any of our used applications (QGIS, Map3d) but anyone using current ProjNET relase can create the corrupted wkt.

I do not see any problems with the changes, due to its just additionaly to the current working solution.
