Answer 1

You can make the form modal by calling Form.ShowDialog()

Don't forget to set Form.DialogResult accordingly on your modal form.

An easy example could be like the following:

Form f = new Form();
f.ShowDialog(this);

The other option is to set the form's TopMost property to true.

Finally, you have the Modal property which will block all other no modal forms from click or keyboard events.

But given that WinForms is a desktop app, you will be able to show it in the desktop of windows 8, but not the new Metro interface.
