When i open my default model class (ErrorViewModel) i found => operator. What is that actually ? What is the use of it ?
using System;
namespace MvcCoreApp.Models
{
    public class ErrorViewModel
    {
        public string RequestId { get; set; }
        public bool ShowRequestId => !string.IsNullOrEmpty(RequestId);
    }
}
What is the use of this => operator here ?
