c# .net system.text.json C#

I'm refactoring my project and I tried several approaches but none seem to work. I'm updating my dependencies and Hey everyone, I'm running into an issue that's driving me crazy. This might be a silly question, but I'm facing a challenge with formatting `DateTime` objects during JSON serialization using `System.Text.Json` in my .NET 6 application. While I want my dates to be serialized in ISO 8601 format, I also need them to include timezone information, specifically UTC. I've tried various approaches, but the default serialization is not meeting my needs, and I'm encountering unexpected results. Here’s a snippet of my code: ```csharp public class Event { public string Name { get; set; } public DateTime EventDate { get; set; } } var myEvent = new Event { Name = "Sample Event", EventDate = DateTime.UtcNow }; var options = new JsonSerializerOptions { WriteIndented = true, // I want to customize the DateTime format here }; string jsonString = JsonSerializer.Serialize(myEvent, options); Console.WriteLine(jsonString); ``` When I run this code, the output for `EventDate` does not include timezone information, and it looks like this: ```json { "Name": "Sample Event", "EventDate": "2023-03-05T12:45:00" } ``` What I was expecting was something like: ```json { "Name": "Sample Event", "EventDate": "2023-03-05T12:45:00Z" } ``` I’ve looked into using `JsonConverter`, but I'm not sure how to implement it correctly with `System.Text.Json`. Can someone provide guidance on how to achieve the desired serialization format or suggest best practices for customizing `DateTime` serialization in this context? Also, I checked the documentation for `System.Text.Json` but couldn't find an explicit example for this specific use case, and I want to ensure I'm following best practices. Any insights would be greatly appreciated! What am I doing wrong? Has anyone dealt with something similar? The stack includes C# and several other technologies. Any examples would be super helpful. How would you solve this? Thanks, I really appreciate it!
