Please share your code and let us know the line throughing the error.

Thank you for replying my message

public class DashboardController : AdminController
{
    private readonly IPersonService _personService;
    public DashboardController(IUnitofWork uow, ILogService logService, IPersonService personService)
                      : base(uow, logService)
    {
        _personService = personService;
    }


    public ActionResult Index() { return View(); }

}

It usually adresses this controller but when I try to fix it, global asax part gives an error, I don't know what to do.

basically employee management system includes more than one layer but the erp system is one layer so when I try to add the employee management system, it becomes more complicated.

my time is limited so I don't know if I can add a new one and like I said, I'm basically a beginner, I'm kinda stuck.

Asp.net mvc is complicated to me, even with the courses, and this projects are so different from one another, is there any sources you can suggest for asp.net mvc and for this particular project?

Add a default constructor in the Controller.

public class DashboardController : AdminController
{
    private readonly IPersonService _personService;

    // Defining the Default constructor.
    public DashboardController()
    {
    }

    // Defining the parameterized constructor.
    public DashboardController(IUnitofWork uow, ILogService logService, IPersonService personService)
                      : base(uow, logService)
    {
        _personService = personService;
    }
 
 
    public ActionResult Index() { return View(); } 
}
