Application not visible in taskbar when using Application.Run()

I am creating a windows application using C#.Net. I am showing a form when starting an applicat开发者_如何学Pythonion using below code :

Form myForm = new MyForm();
Application.Run(myForm);

Application is not appearing in taskbar, but I know its running since I can navigate to the application window using Alt-TAB.

If I use myForm.ShowDialog(), application is visible in taskbar.

What am I missing here?

UPDATE: ShowInTaskbar property is set to true for the form. UPDATE2: FormBorderStyle is set to None

Toggle ShowInTaskbar in your form load event with these two lines:

This.ShowInTaskbar = False
This.ShowInTaskbar = True

It worked for me.

Add Activate() in Form_Shown event.

With .NET Framework 4.6.1, toggling:

this.ShowInTaskBar = false;
this.ShowInTaskBar = true;

causes FormClosing event being fired.

Calling this.Activate() in Shown event works properly.

In my case it was nonmodal form, called to be shown with ShowDialog(), but the request to create and show the form was sent from pipe. When executed by user's click on main form, everything was ok, form was shown and appeared on the taskbar.

You may not set an empty string as windows title during Form load. This is what happened to me today (my window title is retrieved from a file that was missing, and so the window disappeared from the taskbar).
