ASP.NET MVC Core API Serialize Enums to String

Question

How to serialize Enum fields to String instead of an Int in ASP.NET MVC Core 3.0? I\'m not able to do it the old way.

services.AddMvc().AddJsonOptions(opts          


        

Answer 1

some addition:
if use Newtonsoft.Json

Install-Package Microsoft.AspNetCore.Mvc.NewtonsoftJson

services
    .AddControllers()
    .AddNewtonsoftJson(options =>
        options.SerializerSettings.Converters.Add(new Newtonsoft.Json.Converters.StringEnumConverter()));

options.SerializerSettings.Converters

SerializerSettings is necessary
