I get this error when I am trying to debug an ASP.NET MVC 4.0 application using Visual Studio 2012. All the recommendations I saw here were for already deployed applications. Mind you, I am using Windows 7 as OS. How can I fix this?

My global.asax.cs is:

using ObamPortals.Core.Domain.Modules;
using ObamPortal.Web.Modules; 

namespace ObamPortal.Web 
{
    // Note: For instructions on enabling IIS6 or IIS7 classic mode, 
    // visit go.microsoft.com/?LinkId=9394801 

    public class MvcApplication : System.Web.HttpApplication
    {
        public override void Init() 
        {
        }

        protected void Application_Start()
        {
        }
    }
} 

Answer 1

Try this following steps (any)

1.) Close IDE and reopen

2.) Perform a clean build

3.) change the output path in project settings for the web app to Bin (rather than bin/x86/Debug)

Answer 2

Did the app compile properly? Usually the Inherits would include Global in it as : ObamPortal.Web.MvcApplication.Global

You need to make sure the Inherits matches exactly the namespace and class of the global.ascx.cs file.
