Resolved: How can I open app using c# winform and close the winform without closing the opened app?

  public partial class Start_Baseet : System.Windows.Forms.Form
    {
        string MyFile = Environment.CurrentDirectory + "\\Baseet.accde";
        Microsoft.Office.Interop.Access.Application AccApp = new Microsoft.Office.Interop.Access.Application();

        public Start_Baseet()
        {
            InitializeComponent();
        }
        public void OpenDb()
        {
            AccApp.Visible = true;
            AccApp.OpenCurrentDatabase(MyFile, false, "017014a");
            AccApp.RunCommand(AcCommand.acCmdAppMaximize);

        }
        private void Start_Basset_Load(object sender, EventArgs e)
        {
            try
            {
                OpenDb();
            }
            catch
            {
                AccApp.Quit();
                MessageBox.Show("Missing Files", "Error", MessageBoxButtons.OK, MessageBoxIcon.Stop);
            }
            finally
            {
                this.Close();
            }
        }
    }

static void Main()
        {
            Application.EnableVisualStyles();
            Application.SetCompatibleTextRenderingDefault(false);
            //Application.Run(new Start_Baseet());
            Start_Baseet frm = new Start_Baseet();
            frm.Show();
        }

Application.Run(new Start_Baseet());

var frm = new Start_Baseet();
frm.Show();
Application.Run();
