ASP.NET Core - Json serializer settings Enum as string and ignore null values

Startup.cs

public class Startup
{
  public IServiceProvider ConfigureServices(IServiceCollection services)
  {
    services.AddMvc().AddJsonOptions(options =>
    {
      options.SerializerSettings.Converters.Add(new Newtonsoft.Json.Converters.StringEnumConverter());
      options.SerializerSettings.NullValueHandling = Newtonsoft.Json.NullValueHandling.Ignore;
    });
  }
}

You saved me! Thanks bro!

For dotnet 6 a few options were deprecated

        .AddJsonOptions(options =>
        {
            options.JsonSerializerOptions.WriteIndented = true;

            // serialize enums as strings in api responses (e.g. Role)
            options.JsonSerializerOptions.Converters.Add(new JsonStringEnumConverter());

            // ignore omitted parameters on models to enable optional params (e.g. User update)
            options.JsonSerializerOptions.DefaultIgnoreCondition = JsonIgnoreCondition.WhenWritingNull;
        });```
