.Net Core 3.0 possible object cycle was detected which is not supported

Question

I have 2 entities that are related as one to many

public class Restaurant {
   public int RestaurantId {get;set;}
   public string Name {get;set;}
   public          


        

Answer 1

This worked using System.Text.Json

var options = new JsonSerializerOptions()
        {
            MaxDepth = 0,
            IgnoreNullValues = true,
            IgnoreReadOnlyProperties = true
        };

Using options to serialize

objstr = JsonSerializer.Serialize(obj,options);
