Show your code.

Don't! That is the wrong way to do it. A DLL is a support library that provides common routines for multiple applications to access. Your Windows.Form should be in your main application.

If your form is contained inside the DLL, then that's not complicated to create and display it from your app - just add a reference to the DLL to your application project and edit the Program.cs file:

C#

static class Program
        {
        /// <summary>
        /// The main entry point for the application.
        /// </summary>
        [STAThread]
        static void Main()
            {
            Application.EnableVisualStyles();
            Application.SetCompatibleTextRenderingDefault(false);
            Application.Run(new MyDLL.Form1());
            }
        }

If you are trying to display a form from inside a DLL file then as Richard says, that's the wrong way to do it - a DLL should not be concerned with user interface as it could well be used in an environment where Forms are not used: a website for example.
