You can add below code in your Startup.cs file.

public void ConfigureServices(IServiceCollection services)
{
    //...
    services.AddControllers().AddNewtonsoftJson();
    JsonConvert.DefaultSettings = () => new JsonSerializerSettings
    {
        ContractResolver = new CamelCasePropertyNamesContractResolver()
    };
    // ...
}

I am always using this syntax

services.AddControllers()
.AddNewtonsoftJson(options =>
  options.SerializerSettings.ContractResolver =
        new CamelCasePropertyNamesContractResolver());
