Dispose(bool)': no suitable method found to override

[nebrom]

I am developing windows application using C# and Ms sql.
here is my code

namespace rentalMaster
{
    public partial class reportrentstatus : Form
    {
        SqlConnection dbcon = new SqlConnection(ConfigurationManager.ConnectionStrings["mydbcon"].ConnectionString);
      
        public reportrentstatus()
        {
            InitializeComponent();
        }
     

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

here is the designer code

namespace rentalMaster
{
    partial class reportrentstatus
    {
        /// <summary>
        /// Required designer variable.
        /// </summary>
        private System.ComponentModel.IContainer components = null;

        /// <summary>
        /// Clean up any resources being used.
        /// </summary>
        /// <param name="disposing">true if managed resources should be disposed; otherwise, false.</param>
        protected override void Dispose(bool disposing)
        {
            if (disposing && (components != null))
            {
                components.Dispose();
            }
            base.Dispose(disposing);
            
        }
