Implementing the LoginPresenter

Create a new file called LoginPresenter.cs, add it to the Presenter folder in the Chat.Common project, and implement the following:

public class LoginPresenter : BasePresenter
     {
         #region Private Properties
         private ILoginView _view;
         #endregion
         #region IClientsListView
         public interface ILoginView : IView
         {
             event EventHandler<Tuple<string, string>> Login;
             event EventHandler<Tuple<string, string>> Register;
         }
         #endregion
         #region Constructors
         public LoginPresenter(ApplicationState state, INavigationService navigationService)
         {
             _navigationService = navigationService;
             _state = state;
             _webApiAccess = new WebApiAccess();
         }
         #endregion
