How to minimize forms to tray and expand if calculations are running?

Question

C++ / C#

Good afternoon! Can you please tell me how to deploy the program from the tray while the function is running? С#. Or launch the tray context menu while the function is running.

Answer 1

By code..

trayMenu = new ContextMenu();
var items = trayMenu.MenuItems;
items.Add("Open", OnOpenMainWindow);
items.Add("-");
items.Add("Quit", OnQuitApplication);

private void OnOpenMainWindow(object sender, EventArgs e)
{
     Visible = true;
     ShowInTaskbar = true;
}

A long-running function must be moved to a separate thread.
