Question

Upon publishing my MVC 3 Web Application to my website I get an error stating an Object reference not set to an instance of an object.

The ‘error’ line is:
Line 2: ViewBag.Title = "Index";

This is my Index view:

@{
    Layout = "~/Views/Shared/_Layout.cshtml";
}

This is my Home Controller:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;

namespace WebApplication.Controllers
{
    public class HomeController : Controller
    {
        //
        // GET: /Home/

        public ActionResult Index()
        {
            return View();
        }

    }
}

I have uploaded DLL’s:

System.Web.Helpers
System.Web.Mvc
System.Web.Razor
System.Web.WebPages
System.Web.WebPages.Deployment
System.Web.WebPages.Razor

Thanks for any assistance

When you look in /Views/Shared/_Layout.cshtml, you will probably see something like this:

<title>@ViewBag.Title</title>

It is assuming this property has been set somewhere. Usually, you set this in your child views. So the easiest solution is to modify your Index.cshtml view so that it resembles something like this:

@{
     ViewBag.Title = "Title of the page";
     Layout = "~/Views/Shared/_Layout.cshtml";
}
