Save something with JsonDotNet (Json.Net) using Serializable attribute

SaveWithJsonDotNet.cs

static void save(string filePath) {
	// ...
	using (TextWriter writer = File.CreateText(filePath)) {var serializer = getSerializer(errors);
		var errors = new List<string>();
		var serializer = getSerializer(errors);
		serializer.Serialize(writer, snapshot);
		logErrors(errors);
	}
	// ...
}

private static JsonSerializer getSerializer(List<string> errors) {
	JsonSerializer serializer = new JsonSerializer();
	// This next line forces Serializable use.
	serializer.ContractResolver = new MyContractResolver();
	serializer.ConstructorHandling = ConstructorHandling.AllowNonPublicDefaultConstructor;
	serializer.MissingMemberHandling = MissingMemberHandling.Error;
	serializer.Error += (object sender, Newtonsoft.Json.Serialization.ErrorEventArgs args) => {
		errors.Add(string.Format("'{1}' from '{0}'", sender, args.ErrorContext.Error.Message));
	};
	return serializer;
}

private sealed class MyContractResolver : Newtonsoft.Json.Serialization.DefaultContractResolver {
	public MyContractResolver() : base() {
		IgnoreSerializableAttribute = false; // Use SerializableAttribute to determine what to serialize!
	}
