Class is unable to be recognized by other classes and form within same project and name space

Question

I have a public abstract class employee with a constructor I would like to call from a click event in the form for the project. When trying to call the method I get an error that this type or namespace cannot be found, I also get this error if trying to call it from another class within the same project and name space.

Here is the Employee class I have:

using System;
using andrewWoodsAssignment2;
namespace andrewWoodsAssignment2
{


    abstract class Employee
    {
        string employeeFirstName;
        string employeeLastName;
        string employeeNumber;
        string employeeAddress;

        public Employee(string first, string last, string number, string address)
        {
            employeeFirstName = first;
            employeeLastName = last;
            employeeNumber = number;
            employeeAddress = address;
        }

        public override string ToString()
        {
            return "";
        }

    }

}

Here is my form I am trying to call the instructor in:

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Drawing.Text;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;
using andrewWoodsAssignment2;

namespace andrewWoodsAssignment2
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        private void Form1_Load(object sender, EventArgs e)
        {
            
        }

        private void button1_Click(object sender, EventArgs e)
        {
            Employee e1 = new Employee("f", "f", "f", "f");
        }
    }
}

The line in the button1_click is the one causing the error, I have tried checking namespaces, and class names

Here is another class that inherits the employee class which also can't call the constructor or even seem to recognize the inheritance:

using System;
using andrewWoodsAssignment2;
namespace andrewWoodsAssignment2
{


    public class ShiftSupervisor : Employee
    {

        double annualSalary;
        double annualBonus;
        int minimumHoursTraining;
        int trainingHoursAttended;

        public ShiftSupervisor(double annualSalary, double annualBonus, int minimumHoursTraining,
            int trainingHoursAttended)
        {
            
            this.annualSalary = annualSalary;
            this.annualBonus = annualBonus;
            this.minimumHoursTraining = minimumHoursTraining;
            this.trainingHoursAttended = trainingHoursAttended;
        }

        public override string ToString()
        {
            return "";
        }

    }
}

What could be causing this? Here is a screenshot of my files in visual studio

Answer 1

The files listed under "Solution Items" are not part of your project. Move them into your project using drag n drop.

You will still get compiler errors because of other issues with your code, but the visibility issue will be solved.
