ASP.NET MVC on IIS falls through to the static file handler

I have a problem with an ASP.NET MVC site.

These are the details:

  1. ASP.NET MVC 2
  2. ASP.NET 4 integrated pipeline
  3. IIS 7.5 on Windows Web Server 2008 R2

Whenever I make a request for the app I get the "HTTP Error 404.0 - Not Found"-error and the detailed error information shows it is the static file handler that reports the error:

  • Module: IIS Web Core
  • Notification: MapRequestHandler
  • Handler: StaticFile
  • Error Code: 0x80070002

meaning that the request never entered the MVC stack.

I should note that the IIS already serves a ASP.NET MVC 3 on the same app pool and a MVC 2 on a ASP.ENT 2 app pool. So it's the combo ASP.NET 2 on the ASP.NET 4 app pool that are giving me headaches.

Basically I want to upgrade the app from ASP.NET MVC 2 on a ASP.NET 2.0 app pool to a ASP.NET MVC 2 on a ASP.NET 4.0 app pool.

So any ideas?

In my case, a similar error was thrown because StaticFile Handler was disabled / not working properly. I eventually fixed it by removing the handler and re-adding it through the web.config. Also, in case of a 403.3 error, change the RequireAccess-property value from "Write" to "Read"

<configuration>
    <system.webServer>
        <handlers>
           <remove name="StaticFile"
            <add 
                name="StaticFile" 
                path="*" verb="*" 
                modules="StaticFileModule,DefaultDocumentModule,DirectoryListingModule" 
                resourceType="Either" 
                requireAccess="Read" />
        </handlers>
    </system.webServer>
</configuration>
