XNA Game class Error

Question

I have project, inside there is background.cs class and game1.cs class, thats my background.cs class code:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using Microsoft.Xna.Framework.Graphics;
using Microsoft.Xna.Framework;

 namespace Rocket
 {
    class Backgrounds
  {
    public Texture2D texture;
    public Rectangle rectangle;
    public void Draw(SpriteBatch spriteBatch){
        spriteBatch.Draw(texture, rectangle, Color.White);
    }
    class Scrolling : Backgrounds{
        public Scrolling(Texture2D newTexture, Rectangle newRectangle){
            texture = newTexture;
            rectangle = newRectangle;
        }
        public void Update(){
            rectangle.X -= 3;
        }

    }
  }
}

and thats game1.cs class code (starting where I get error):

using System;
using System.Collections.Generic;
using System.Linq;
using Microsoft.Xna.Framework;
using Microsoft.Xna.Framework.Audio;
using Microsoft.Xna.Framework.Content;
using Microsoft.Xna.Framework.GamerServices;
using Microsoft.Xna.Framework.Graphics;
using Microsoft.Xna.Framework.Input;
using Microsoft.Xna.Framework.Media;

namespace Rocket
{
/// <summary>
/// This is the main type for your game
/// </summary>
public class Game1 : Microsoft.Xna.Framework.Game
{
    GraphicsDeviceManager graphics;
    SpriteBatch spriteBatch;

    Scrolling scrolling1;
    Scrolling scrolling2;

' So, Scrolling scrolling1; is underlined, (as second one), it says that class Scrolling could not be found, but it exists! I am noob in XNA and I cant find why it isn't working. any help will be ok!

Why do you have your Scrolling class nested into Backgrounds class in background.cs? The default visibility for nested classes in C# is private and therefore it is not visible to the Game1 class.

You should put this

class Scrolling : Backgrounds{
    public Scrolling(Texture2D newTexture, Rectangle newRectangle){
        texture = newTexture;
        rectangle = newRectangle;
    }
    public void Update(){
        rectangle.X -= 3;
    }

}

into a file scrolling.cs. This gives Scrolling and Background the default visibility for classes (internal) which should work for your example.

You should to specify the visibility of classes explicitly. Have a look at: https://msdn.microsoft.com/en-us/library/ms173121.aspx
