How to use service(BLL) in Form(windowsForm) With DI

I have a WindowsForm Project With this design :

DAL(GenericRepository => UnitOfWork) => BLL(Service) => UI

And EntityFramWork, Interface, GenericRepository, Dependency Injection

My Code in Repository(DAL) :

public class Repository : RepositoryBase, IDisposable, IRepository where T : class
{
private readonly DbSet dbSet;
private bool disposed = false;
public Repository(GlobalERPEntities dbContext)
{
DBContext = dbContext;
dbSet = DBContext.Set();
}
public virtual IEnumerable GetAll()
{
return dbSet.ToList();
}

UnitOfWork(DAL) :

Service(BLL) :

MyForm(UI) :

using (Service_HR_Person SrvPerson = new Service_HR_Person())
{
SrvPerson.Delete(base.rowid);
try
{
SrvPerson.Save();
MessageManager.Show(Enums.MessageBoxType.InformationTransactionSuccessfully);
}
catch (Exception ex)
{
MessageManager.Show(ErrorManager.ProccessException(ex), Enums.MessageBoxType.Error);
}
}

Iknow should not use DAL Layer in UI layer and BLL is between DAL and UI

but i have error in ui

Service_HR_Person say need an arguman in () that is unitofwork but we should not use unitofwork in UI

please help me with code

thankyou

Hi, yes in this case you need DI to take care of injecting the unit of work object. For this, you need to choose any one of the DI container tools like Unity and register your objects over there.

Please find my complete tutorials for implementing such functionality here
