Then completed all manually conversion steps from the tutorial. Now after doing all this when i run MVC – 4 project i got this following exception page :

Can anybody please explain me how to solve this issue?

Answer 1

The class name in the inherits attribute in the Global.asax (right click view markup) should match the class name and namespace in the Global.asax.cs

Right now you have

<%@ Application Codebehind="Global.asax.cs" 
                Inherits="SiteBuilderAzure_MVC_4.MvcApplication" Language="C#" %>

But I guess in your Global.asax.cs you have your MvcApplication in different namespace:

namespace SomeOtherNamespace
{
    public class MvcApplication : System.Web.HttpApplication
    {
    }
}

So just make sure that you use the correct MvcApplication namespace in your Inherits
