I have two entities: Employeees and Projects which have the relationship of Many-to-Many. I defined a ProjectEmployee for that, but when I add migration, it still creates a EmployeesProjects. Why does this happen and how can I fix that? Thank you guys!

Here is the Employees.cs

using Day1.Model;
using System.ComponentModel.DataAnnotations;

public class Employees
{
    [Required]
    public int Id { get; set; }
    [Required]
    [MaxLength(50)]
    public string Name { get; set; }
    public int DepartmentId { get; set; }
    public DateTime JoinedDate { get; set; }
    public Salaries Salary { get; set; }
    public IList<Projects> Projects { get; set; }
    public Departments Department { get; set; }
    public IList<ProjectEmployee> ProjectEmployees { get; set; }
}

Projects.cs

using Day1.Model;
using System.ComponentModel.DataAnnotations;

public class Projects
{
    [Required]
    public int Id { get; set; }
    [Required]
    [MaxLength(50)]
    public string Name { get; set; }
    public IList<Employees> Employees { get; set; }
    public IList<ProjectEmployee> ProjectEmployees { get; set; }
}

The ProjectEmployee.cs

namespace Day1.Model
{
    public class ProjectEmployee
    {
        public int ProjectId { get; set; }
        public Projects Project { get; set; }
        public int EmployeeId { get; set; }
        public Employees Employee { get; set; }
        public bool Enable { get; set; }
    }
}

Here is the migration:

using System;
using Microsoft.EntityFrameworkCore.Migrations;

#nullable disable

#pragma warning disable CA1814 // Prefer jagged arrays over multidimensional

namespace Day1.Migrations
{
    /// <inheritdoc />
    public partial class InitialCreate : Migration
    {
        /// <inheritdoc />

            migrationBuilder.CreateTable(
                name: "Departments",
                columns: table => new

                constraints: table =>

I tried manually deleting the EmployeesProjects table create code block in migration, but it would still generate it when I add migration. I searched every files to see if I configed the model anywhere, but the result wasn’t so positive.
