I can't create instances of my new form in C# winforms... any idea why?

[Slippy]

When I use the following code...

Form1 frmTest = new Form1();

I get a new instance of Form1...

I have added a form called Form2 to the project, but when I use the following code...

Form2 frmTest1 = new Form2();

I get the following error :


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

its definitely called Form2, and I have even tried this with other forms, like Form3 etc, but all I can do is Form1... any help?

Thanks in advance.
