In .NET Core 1.0, you can set this as a global setting in your Startup.cs file:

using System.Buffers;
using Microsoft.AspNetCore.Mvc.Formatters;
using Newtonsoft.Json;

// beginning of Startup class

    public void ConfigureServices(IServiceCollection services)
    {
        services.AddMvc(options =>
        {
            options.OutputFormatters.Clear();
            options.OutputFormatters.Add(new JsonOutputFormatter(new JsonSerializerSettings(){
                ReferenceLoopHandling = ReferenceLoopHandling.Ignore,
            }, ArrayPool.Shared));
        });
    }
