asp.net core - Controller.json set Serialization.ReferenceLoopHandling

Question

is there a way to set Controller.Json ReferenceLoopHandling property?

It is currently causing a self referencing loop when parsing entities with navigation properties defined on both ends. This problem is solved by setting

ReferenceLoopHandling = Newtonsoft.Json.ReferenceLoopHandling.Ignore;

Is there a way to do this for Controller.Json method?

I found this piece of code, but it does not seem to work.

services.Configure<MvcOptions>(option =>
        {
            option.OutputFormatters.Clear();
            var jsonOutputFormatter = new JsonOutputFormatter();
            jsonOutputFormatter.SerializerSettings.ReferenceLoopHandling = Newtonsoft.Json.ReferenceLoopHandling.Ignore;

            option.OutputFormatters.Insert(0, jsonOutputFormatter);
        });

I think that a prettier solution for this is to add JsonOptions in your ConfigureServices like:

services.AddMvc().AddJsonOptions(options =>
{
    options.SerializerSettings.ReferenceLoopHandling = 
                               Newtonsoft.Json.ReferenceLoopHandling.Ignore;
});
