Description

The examples show how to serialize a complex object, but they do not show how to deserialize it. They only show that the root object is deserialized. I suggest adding code like the following to show that the child objects are also deserialized:

		if (weatherForecast != null)
		{
			if (weatherForecast.DatesAvailable != null)
			{
				foreach (DateTimeOffset dateTimeOffset in weatherForecast.DatesAvailable)
				{
					Console.WriteLine(value: $"DateAvailable: {dateTimeOffset}");
				}
			}

			if (weatherForecast.TemperatureRanges != null)
			{
				foreach (KeyValuePair<string, HighLowTemps> weatherForecastTemperatureRange in weatherForecast.TemperatureRanges)
				{
					Console.WriteLine(value: $"TemperatureRange: {weatherForecastTemperatureRange.Key}, {weatherForecastTemperatureRange.Value.Low} - {weatherForecastTemperatureRange.Value.High}");
				}
			}

			if (weatherForecast.SummaryWords != null)
			{
				foreach (string summaryWord in weatherForecast.SummaryWords)
				{
					Console.WriteLine(value: $"SummaryWord: {summaryWord}");
				}
			}
		}

Output would then be:
Date: 8/1/2019 12:00:00 AM +02:00
TemperatureCelsius: 25
Summary: Hot
DateAvailable: 8/1/2019 12:00:00 AM +02:00
DateAvailable: 8/2/2019 12:00:00 AM +02:00
TemperatureRange: Cold, -10 - 20
TemperatureRange: Hot, 20 - 60
SummaryWord: Cool
SummaryWord: Windy
SummaryWord: Humid

It would also be extremely helpful to have an example on how to deserialize interfaces. E.g. like at https://gist.github.com/tonysneed/5e7988516b081d454cde95b5d729e1af
