MicrosoftSpatialGeoJsonConverter doesn't support Microsoft.Spatial.GeographyPolygon

True {“type”:“Point”,“coordinates”:[20.1,20]} False

is the LinqPad output for the code below. MicrosoftSpatialGeoJsonConverter seems to be handling Point, why not Polygon?

void Main()
{
	GeographyPoint geographyPoint = GeographyPoint.Create(20, 20.1);
	
	GeographyPolygon geographyPolygon = GeographyFactory.Polygon().Ring(10, 10).LineTo(30, 10).LineTo(30, 30).LineTo(10, 30).LineTo(10, 10).Build();
	
	WriteObject(geographyPoint);
	
	WriteObject(geographyPolygon);
}

void WriteObject(object obj)
{
	MicrosoftSpatialGeoJsonConverter converter = new ();

	converter.CanConvert(obj.GetType()).Dump();
	
	JsonWriterOptions writerOptions = new () { Indented = false, };

	using MemoryStream stream = new ();
	
	using Utf8JsonWriter writer = new (stream, writerOptions);
	
	JsonSerializerOptions options = new (JsonSerializerDefaults.General);

	converter.Write(writer, obj, options);

	writer.Flush();

	string json = Encoding.UTF8.GetString(stream.ToArray());

	json.Dump();
}

Sure, I’ll work on that tonight. Thanks.
