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

Question

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) :

public class UnitOfWork : RepositoryBase, IUnitOfWork, IDisposable
   {
       private Dictionaryobject> repositories;
       private bool disposed = false;

       public UnitOfWork(GlobalERPEntities dbContext)
       {
           DBContext = dbContext;
       }

       public IRepository Repository() where T : class
       {
           if (repositories == null)
           {
               repositories = new Dictionaryobject>();
           }

           if (repositories.Keys.Contains(typeof(T)) == true)
           {
               return repositories[typeof(T)] as Repository;
           }
           Repository repo = new Repository(DBContext);
           repositories.Add(typeof(T), repo);
           return repo;
       }

 Service(BLL) :

public class Service_HR_Person : IService_HR_Person ,  IDisposable
   {
       private readonly IUnitOfWork UnitOfWork;

       public Service_HR_Person(IUnitOfWork unitOfWork)
       {
           UnitOfWork = unitOfWork;
       }

       public virtual IEnumerable GetAll()
       {
           return UnitOfWork.Repository().GetAll().ToList();
       }

 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

using (Service_HR_Person SrvPerson = new Service_HR_Person())

 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
