How does the configuration binder handle nested objects and arrays when binding a JSON section to a strongly-typed C# class?

The binder uses reflection to match configuration keys (flattened into a colon-delimited hierarchy internally) to corresponding property names, recursively binding nested objects, and mapping JSON arrays to numerically-indexed keys (Items:0, Items:1) that bind to List<T> or array properties -- requiring the target class to have public settable properties matching the configuration structure.

// appsettings.json
{
  "Settings": {
    "MaxRetries": 3,
    "Endpoints": ["https://a.com", "https://b.com"]
  }
}

public class Settings {
    public int MaxRetries { get; set; }
    public List<string> Endpoints { get; set; } = new();
}
