In this post, I will tell you about Refresh PartialView Automatically in ASP.NET MVC 6.  First thing you can do is Create a MVC app on Visual Studio and then add two Classes to your model folder.

using System.ComponentModel.DataAnnotations;
namespace AutoRefresh.Models
{
    public class Employee
    {
        [Key]
        public int Id { get; set; }
        public string Name { get; set; }
        public string ImagePath { get; set; }
    }
}

using System.Data.Entity;
namespace AutoRefresh.Models
{
    public class DemoContext:DbContext
    {
        public DbSet<Employee> employee { get; set; }
    }
}

Now, add a Home Controller and write the following code:
using System;
using System.Linq;
using System.Web.Mvc;
using AutoRefresh.Models;
using System.Web.UI;
namespace AutoRefresh.Controllers
{
    public class HomeController : Controller
    {
        public ActionResult Index()
        {
            using (DemoContext dbObj = new DemoContext())
            {
               var empList = dbObj.employee.ToList();
                return View(empList);
           }
    }
        [OutputCache(Location = OutputCacheLocation.Client, VaryByParam = "none", Duration = 2)]
        public PartialViewResult _employeeShow()
       {
            using (DemoContext dbObj = new DemoContext())
            {
                var empList = dbObj.employee.ToList();
                int MinId = empList.Min(a => a.Id);
                int MaxId = empList.Max(a => a.Id);
               //generate a random number
                int GetRandomId = new Random().Next(MinId, (MaxId + 1));
                var getRandomemployee=empList.Find(a => a.Id == GetRandomId);
                return PartialView("_employeeShow", getRandomemployee);
            }
        }
     }
}

From the above code, I used OutputCache to get Data from Cache. Next step, add a PartialView _employeeShow to show the Employee.
@model AutoRefresh.Models.Employee
<div class="divEmployee" style="margin-left: 50px;">
    <img src="@Model.ImagePath" width="100" height="100" />
    <span>@Model.Name</span>
</div>

Now , create the Index View. With this view we will load our PartialView.
@model IEnumerable<AutoRefresh.Models.Employee>
@{
    ViewBag.Title = "Index";
}
<script src="~/Scripts/jquery-2.1.1.min.js"></script>
<script type="text/javascript">
    $(document).ready(function () {
        setInterval(function () {
            $('#Employee').load('/Home/_employeeShow')
        },2000);
    });
</script>
<h2>Employee</h2>
<div id="Employee">
    @Html.Partial("_employeeShow", Model.FirstOrDefault())
</div>

Using Jquery, I’m loading the PartialView in every 2 seconds.
