Question

I want to lear to use mvc4 on vs11 beta professional version

1. I created an ASP.NET MVC 4 WEB APPLICATION
2. I select the Empty template

3. I create a controller called c1

   Namespace MvcApplication3
      Public Class c1
         Inherits System.Web.Mvc.Controller
   
       '
       ' GET: /c1
   
       Function Index() As ActionResult
           Return View()
       End Function
   
   
       Function Hello() As String
           Return "Hello"
       End Function
   
      End Class
   End Namespace
   

4. I run the application and in the browser URL i write “http://localhost:49653/c1/hello”
   but i get this error:

Server Error in ‘/’ Application.

The resource cannot be found. Description: HTTP 404. The resource
you are looking for (or one of its dependencies) could have been
removed, had its name changed, or is temporarily unavailable. Please
review the following URL and make sure that it is spelled correctly.

Requested URL: /c1/hello

What am I doing wrong?? Why it is not working?

Answer 1

With the DefaultControllerFactory its not enough to inherit from System.Web.Mvc.Controller but your controller name have to end with the word “Controller” (it’s a built in convention)

Rename your c1 to c1Controller and it should work:

Public Class c1Controller
      Inherits System.Web.Mvc.Controller
