publish asp.net mvc 4 site gave 404 on IIS 6 host - asp.net-mvc-4

Question

Newly created ASP.Net MVC 4, C# project with VS Express 2012 for Web, target .Net Framework version 4.0 (same as the remote host).
Debugging directly through VS is find. After publishing to local folder, [original:There is no .aspx generated, only sitename.dll, there were even original .cshtml files] and copying to IIS Express C:\inetpub\www folder, http://localhost/Home is fine.
But when I upload everything to host (according to info.aspx, server info: IIS 6.0, .Net Version 4.0.30319.239), http://domain/Home gave page cannot be found 404 error, which seems like a routing problem.
Here is my Web.config:

Static files html, gif and simple *.aspx*s are fine. Only MVC pathes /Home/Index and /Home gave 404 - not found error.
What should I change to make it work?

Answer 1

What you got on the local side is correct. .Csthml files are the web pages when using Razor.
Did you set up IIS correctly on the Host? You have to create a website and make sure that the Application pool is using the correct .Net Version.

Answer 2

Using ASP.NET MVC with Different Versions of IIS (C#) had it step by step for shared host IIS 6 to use MVC routing. It was even on the VS generated page, but I had ignored it.
So for anyone else having the similar headache, here is important parts.
1. Assuming it is a shared host that we can't do much server config.
2. IIS 6, .Net 4.0, and possibly Windows 2003
In our Asp.Net MVC 4, global.asax.cs register routs
public static void RegisterRoutes(RouteCollection routes)
{
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
routes.MapRoute(
"Default",
"{controller}.aspx/{action}/{id}",
new { action = "Index", id = "" }
);
routes.MapRoute(
"Root",
"",
new { controller = "Home", action = "Index", id = "root" }
);
}
protected void Application_Start()
{
RegisterRoutes(RouteTable.Routes); //RouteConfig.RegisterRoutes didn't work
}
Since .aspx files are directed to ASP.Net for processing, these routing rules will catch http://domain/home.apspx/index to invoke HomeController.Index.
If there is a need to ignore some files, just prepend a ignoring rule like below
routes.IgnoreRoute("Content/{*pathInfo}");
routes.IgnoreRoute("info.aspx");
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
