C# Setting Form 2 as Startup

Question

in c#, i want to set forum 2 as startup form from program.cs, but when i try to change the code piece below i get such an error

before changing:

static void Main()
        {

            Application.EnableVisualStyles();
            Application.SetCompatibleTextRenderingDefault(false);
            Application.Run(new Form1());
        }

after changing:

static void Main()
    {

        Application.EnableVisualStyles();
        Application.SetCompatibleTextRenderingDefault(false);
        Application.Run(new Form2());
    }

the error is : The type or namespace name 'Form2' could not be found (are you missing a using directive or an assembly reference?)

All my changes are to write "Form2" instead of "Form1"

Well where does `Form2` actually 'live'? Within what namespace? (Open the designer up, view the code behind the designer, look at the top, what's the namespace? How does this differ from `Form1`?) — Arran, Jun 26 '13 at 09:35
Check if the namespace inside the file Form2.cs is the same of Form1.cs — Steve, Jun 26 '13 at 09:35
Did You add Form2 to the project with the context menu of the project tree ? — icbytes, Jun 26 '13 at 09:36
they got different namespaces but they are in the same project, — Abdülber Kaya, Jun 26 '13 at 09:42
@AbdülberKaya, then you need to add that namespace as one of your `using`'s within `Program.cs`. — Arran, Jun 26 '13 at 09:43

one's namespace is WindowsFormsApplication1, and the other one's Uploader — Abdülber Kaya, Jun 26 '13 at 09:43

According to your comments, your form Form2 lives within the Uploader namespace. If that is the entire namespace then:

At the top of Program.cs, add in:

 using Uploader;

or

If you are using Visual Studio, it has a handy feature that allows you to right-click on where the error occurs (the Application.Run line), and it will give you the option to automagically add in the using for you.
