Question

i having error throw on View page and i think i am passing wrong type, can anybody please correct me – thanks.

The model item passed into the dictionary is of type ‘System.Collections.Generic.List1[App.Domain.Model.Interface.IPerson]' but this dictionary requires a model item of type 'System.Collections.Generic.IEnumerable1[App.Domain.Service.PersonService]’.

MyService looks like this….

namespace App.Domain.Service
{
    public class PersonService :  IPersonService
    { 
        private IPersonRepository _personRepository;
        public PersonService(IPersonRepository personRepository)
        {
            _personRepository = personRepository; 
        }

        public List<IPerson> GetPerson()
        {            
            return _personRepository.GetHost();
        } 
    }
}

myView look like this…

<%@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/Site.Master" 
Inherits="System.Web.Mvc.ViewPage<IEnumerable<App.Domain.Service.PersonService>>" %>

my controller look like this…

 public ActionResult GetPersons()
        {
            IPersonRepository personRepo = new PersonRepository();
            PersonService person = new PersonService(personRepo);
            IList<IPerson> p  = person.GetPerson(); 
            return View(p);
        }

You are sending the wrong type to the View()
In your View decleration says App.Domain.Service.PersonService, but in your View you are sending it a View(IPerson).
If you want to send an IPerson to your view the tag should read like:

<%@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage<IEnumerable<App.Domain.Model.Interface.IPerson>>" %>
