Serializing in C#

Object to JSON in one call with System.Text.Json.

using System.Text.Json;

var config = new { Name = "typestar", Port = 8080, Debug = false };

// serialization is one call; options shape the output
Console.WriteLine(JsonSerializer.Serialize(config));

var pretty = new JsonSerializerOptions { WriteIndented = true };
Console.WriteLine(JsonSerializer.Serialize(config, pretty));

How it works

1. JsonSerializer.Serialize handles anonymous types too.
2. Options are their own object; WriteIndented pretty-prints.
3. The default output is compact, made for wires not eyes.
