I have access to a REST web service that returns geometries in WKT. How would I draw those on an ESRI map. I see that I can take a WKID and convert to an ESRI SpatialReference. I see that I can take ArcGIS JSON and convert it to an ESRI Geometry with the FromJson() method. But I do not see a way to convert WKT of a geometry, like "POINT ( -148.69621300 70.49185500)", to an ESRI Geometry. Surely, we should not have to write our own WKT parser to manually convert to ESRI Geometry??
