C# 10 - advanced patterns with Custom JSON Serialization Using System.Text.Json
I'm learning this framework and I'm working with an scenario with custom JSON serialization in C# 10 using `System.Text.Json`. I have a class that contains a few properties, and I implemented a custom converter to format one of the properties specifically. However, despite registering the converter, the output JSON is not reflecting the expected format. Here's my code snippet: ```csharp public class Person { public string Name { get; set; } [JsonConverter(typeof(CustomDateConverter))] public DateTime BirthDate { get; set; } } public class CustomDateConverter : JsonConverter<DateTime> { public override void Write(Utf8JsonWriter writer, DateTime value, JsonSerializerOptions options) { writer.WriteStringValue(value.ToString("yyyy-MM-dd")); } public override DateTime Read(ref Utf8JsonReader reader, Type typeToConvert, JsonSerializerOptions options) { return DateTime.Parse(reader.GetString()); } } var person = new Person { Name = "John Doe", BirthDate = new DateTime(1990, 1, 1) }; var options = new JsonSerializerOptions { WriteIndented = true }; var json = JsonSerializer.Serialize(person, options); Console.WriteLine(json); ``` When I run this code, I expect the `BirthDate` to be serialized as `"BirthDate": "1990-01-01"`, but instead, I see it as `"BirthDate": "1/1/1990 12:00:00 AM"`. I've made sure that the `CustomDateConverter` is correctly registered, and I tried using `JsonSerializerOptions.Converters.Add(new CustomDateConverter())`, but it didn’t resolve the scenario. Additionally, I verified that the `JsonConverter` attribute is correctly applied. Could anyone guide to understand why the custom converter isn't taking effect during serialization? I've checked the relevant documentation, and I feel like I'm missing something subtle. My development environment is CentOS. Is there a simpler solution I'm overlooking?
