.NET Core: Remove null fields from API JSON response

Question

On a global level in .NET Core 1.0 (all API responses), how can I configure Startup.cs so that null fields are removed/ignored in JSON responses?

Using Newtonsoft.Js

In Asp.Net Core you can also do it in the action method, by returning

return new JsonResult(result, new JsonSerializerOptions
{
   IgnoreNullValues = true,
});
