setup dialog? (1 Viewer)

[Andy M]

I programmed the example plugin from the Wiki. It works. Now I tried to substitute the message box „Nothing to configure, this is just an example“ for my own window to get real setup dialog for my plugin.
I created a new Window named “OptionenDialog” and tried to instantiate it and show it instead of the massage box. Then I get an error message in Visual Studio 2010. The namspacename “OptionenDialog” in not fond.

Example sours code

// show the setup dialog
        public void ShowPlugin()
        {
            //MessageBox.Show("Nothing to configure, this is just an example");
        }

My sours code

// show the setup dialog
        public void ShowPlugin()
        {
            OptionenDialog setup = new OptionenDialog();
            setup.ShowDialog();
        }

Can anyone help me with to create a setup dialog?
