any idea about type mapping of box2/3d?

[sharkAndshark]

Am wondering following way dealing with Input/output about box2/3d is too dirty and evil?

[Sql.Expression("ST_Box2dFromGeoHash({0},{1})::geometry",ServerSideOnly = true)]
public static NTSG STBox2dFromGeoHash(string geohash, int precision)
{
    throw new InvalidOperationException();
}

Will investigate it in future; now I want to complete implementation for most methods with geometry type first of all. Your suggestion can be a last resort, if there will be no way to work with box2d PostGIS type in underlying NTS type system.
