STStartPoint() is the equivalent of STPointN(1).
The following example creates a LineString instance and uses STStartPoint() to retrieve the start point of the instance.
DECLARE @g geography;
SET @g = geography::STGeomFromText('LINESTRING(-122.360 47.656, -122.343 47.656)', 4326);
SELECT @g.STStartPoint().ToString();
