How can I match XNA with Windows Form in VS 2019?

Question

I'm trying to create a music player with an audio visualizer starting from a windows game project on VS 2019. To do so I created a custom display, draggable from the toolbox, in order to put it inside a form.

From tutorials I've seen it is necessary to include three classes from GraphicsDevice and I've done it, but when I put them inside the code, the Display class does not inherit and VS does not recognize the keywords.

To be precise WinFormsGraphicsDevice is marked as an error, and its methods as well.

Does anybody have any hints about this?

using System;
using System.Windows.Forms;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace WindowsGame2.CustomControls
{
    public class Display : WinFormsGraphicsDevice.GraphicsDeviceControl
    {
        protected override void Initialize()
        {
            
        }

        protected override void Draw()
        {
            GraphicsDevice.Clear();
        }
    }
}
