Presenter: public interface IPresenter
    {

        Type TypeOfModel { get; }
    }

 

the common actions for presenter is that: know the IModel and IView

 public abstract class Presenter<ViewType, IModelType> : IPresenter
        
//where IModelType : IServiceInterface
    {
        
/// <summary>
        
/// The view

        protected ViewType view;/// <summary>

        protected IModelType model;/// <summary>
        
/// Gets a value indicating whether this <see cref="Presenter&lt;IViewType,
IModelType&gt;"/>
is initialized.
        
/// Only when both view and model are binded, a presenter is initialized.
        
/// </summary>
        
/// <value><c>true</c> if initialized; otherwise, <c>false</c>.</value>
        public bool Initialized
        {
            
get
            {
                
return view != null && model != null;
            }
        }
#region IPresenter Members/// <summary>
        
/// Binds the view.
        
/// </summary>
        
/// <param name="view">The view.</param>
        public void BindView(object view)
        {
            Check.Require(view 
!= null"view could not be null.");
            Check.Require(
typeof(ViewType).IsAssignableFrom(view.GetType()),
"
view's type does not match Presenter's view type.");
            
this.view = (ViewType)view;
        }
/// <summary>
        
/// Binds the model.
        
/// </summary>
        
/// <param name="model">The model.</param>
        public void BindModel(object model)
        {
            Check.Require(model 
!= null"model could not be null.");
            Check.Require(
typeof(IModelType).IsAssignableFrom(model.GetType()),
 
"model's type does not match Presenter's model type.");
            
this.model = (IModelType)model;
        }
/// <summary>
        
/// Gets the type of the view.
        
/// </summary>
        
/// <value>The type of the view.</value>
        public Type TypeOfView
        {
            
get
            {
                
return typeof(ViewType);
            }
        }
/// <summary>
        
/// Gets the type of the model.
        
/// </summary>
        
/// <value>The type of the model.</value>
        public Type TypeOfModel
        {
            
get
            {
                
return typeof(IModelType);
            }
        }
#endregion
    }

likewise, you can have several IModel for a presenter as well.

then we can have a PresenterFactory responsible for the action "BindModel" and "BindView"
