You are absolutely correct! My apologies. I only provided the initial Login Form setup. Let's continue building the application based on the requirements. We will now add the Create Account Form, the Management Form with its tabs, the Add/Edit Listing Form, and set up the structure for the unit test. This will involve creating several new forms and adding more logic. We'll use placeholder data and logic where database interaction would normally occur. using System; using System.Windows.Forms; namespace WorldSkillsApp { static class Program { ///

[STAThread] static void Main() { Application.EnableVisualStyles(); Application.SetCompatibleTextRenderingDefault(false); // Ensure we always start with the Login Form Application.Run(new LoginForm()); } // Placeholder for global user state if needed (alternative to passing data) // public static User CurrentUser { get; set; } // public static bool IsEmployeeSession { get; set; } } } namespace WorldSkillsApp { partial class LoginForm { ///
