Suppress properties with null value on ASP.NET Web API

Question

I\'ve created an ASP.Net WEB API Project that will be used by a mobile application. I need the response json to omit null properties instead of return them as property

For ASP.NET Core 3.0, the ConfigureServices() method in Startup.cs code should contain:

services.AddControllers()
    .AddJsonOptions(options =>
    {
        options.JsonSerializerOptions.IgnoreNullValues = true;
    });
