Hi!

I have the following problem: in a Windows Application project (c#) I have a form inherited from System.Windows.Forms.Form, and another one inherited from the first.

public class Form1 : System.Windows.Forms.Form
    {
        public Form1()
        {
            InitializeComponent();
        }
         ....

public class TestForm : Form1
    {
         ...

When I enter the design mode for the 'TestFrom' class, I always get an error message: "the base class couldn't be loaded...".
Had I forgot something?

Thanks,

Best regards,
Stephan
