Glad to help!

It is always a good idea to formally close the question, if the issue is resolved. ALWAYS keep the habit of 'tracking to the closer'. That would make you a real professional.

If you still have any questions, please do not hesitate to get in touch.

You have put the highlighted (bold) method inside the namespace but outside the class, which is not allowed.

All methods and properties MUST BE part of class. May be it is just that you didn't realise where the class ends.

Below is modified code:
using System;
using System.Collections.Generic;
using System.IO;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace Sauna
{
  class SaunaApp
  {
    private List staff;
    private List
articles;

    public SaunaApp()
    {
      staff = new List();
      articles = new List
();
      FillWithData();
    }

    public void FillWithData()
    {
      articles.Add(new Meat("Steak", 3.2m, DateTime.Now));
      articles.Add(new Meat("Grill", 3.9m, DateTime.Now.AddDays(3)));

      articles.Add(new Fish("Salamon", 8.3m, DateTime.Now.AddDays(1)));
      articles.Add(new Fish("rab", 8.3m, DateTime.Now.AddDays(2)));

      articles.Add(new Towel("Large", 2.5m));
      articles.Add(new Towel("Small", 2.5m));

      articles.Add(new Fish("Salamon", 8.3m, DateTime.Now.AddDays(1)));
      articles.Add(new Fish("Krab", 8.3m, DateTime.Now.AddDays(2)));

      articles.Add(new Towel("Large", 8.3m));
      articles.Add(new Towel("Small", 8.3m));
