Found the answer. If the co-ordinates are reversed the polygon displays as it should. I guess my original data had some polygons that were reversed.
.ReorientObject() does this automatically
Question
I'm trying to import UK postcode zones from WKT to SQLServer 2012. Most are fine but there's a few that produce an very large polygon (best I can explain it).
When using QGIS the WKT below displays as it should.
MULTIPOLYGON (((-2.255068 53.669782,
-2.262690 53.651819,
-2.276995 53.676325,
-2.255068 53.669782)))
but when using geography::STGeomFromText(#above WKT#, 4326) the spatial results window shows a grid filled with a square polygon not the area displayed in QGIS.
Any idea why?
