I have an app that runs Form1 (by default). How i would like to add another form Form2 and this form must be shown first. Hot to do that?
For example Form2 will contain languages so the user must first chose language, then use the app.

The answer is: in your Main method (entry point), you have something like:

C#

Application.Run(new Form1());

Replace it to Form2. This call defines what form is the main one.

However, this is not so simple. You don't explain what exactly do you want, and that could make a big difference. What happens if you show other forms? The main form is still main: when you close it, you exit the whole application. If you want this behavior on other forms, you would need to use Application.Exit. If you want to keep a main form main, and show other forms at the same time, this is not a problem.

But if your goal is to show one form at a time (a kind of a wizard behavior), you could do one of the two things: 1) repeat the code shown above in the Main method for all forms you want; in this case, you should calculate what to do next, depending on some "result" of the operation on a previous form; such "semi-sequential" scenario will be very limited anyway; 2) use only one form; in this case, what you planned to be forms should be different panels; show one panel at a time on the same form, making other panels hidden.
