How to do this in repl.it please? Or maybe Visual Studio?

//Objec initialization

 public class Bird
 {
   public string Name{get; set;}
   public string Color{get; set;}
   public int Sightings{get; set;}




 }

using System;
using System.Linq;
using System.Collections.Generic;





class MainClass {
  public static void Main (string[] args) {

    List<Bird> birds = new List<Bird>
        {
          new Bird
          {
            Name = "Cardinal",
            Color = "Red",
            Sightings = 3
          },
          new Bird
          {
            Name = "Dove",
            Color = "White",
            Sightings = 2
          }

        };
    var canary = new Bird 
    {
      Name = "Canary", 
      Color = "yellow",
      Sightings = 0
    };

    birds.Add(canary);

    foreach(Bird bird in birds){
      Console.WriteLine(bird.Name + " " + bird.Color + " " + bird.Sightings);
    }

     query = from b in birds where b.Color == "Red" select b;

      Console.WriteLine(query);


  }
}

 query = from b in birds where b.Color == "Red" select b;

      Console.WriteLine(query);
