Example Usage

C#:

using Cratis.Geospatial;
using System.Text.Json;

var coordinate = new Coordinate(10.5, 20.3);
var json = JsonSerializer.Serialize(coordinate);
// {"longitude":10.5,"latitude":20.3}

TypeScript:

import { Coordinate, JsonSerializer } from '@cratis/fundamentals';

const coordinate = new Coordinate(10.5, 20.3);
const json = JsonSerializer.serialize(coordinate);
// {"longitude":10.5,"latitude":20.3}
