ASP NET MVC on IIS 7 5

Question

I m running Windows 7 Ultimate  64 bit  using Visual Studio 2010 RC  I recently decided to have VS run debug my apps on IIS rather than the dev server that comes with it    However  every time I try to run an MVC app  I get the following error      HTTP Error 403 14 - Forbidden The Web server is configured to not list the contents of this directory  Detailed      Error Information      Module    DirectoryListingModule      Notification  ExecuteRequestHandler      Handler   StaticFile Error      Code  0x00000000 Requested      URL   http   localhost 80 mySite       Physical   Path  C  myProject mySite       Logon Method  Anonymous Logon      User  Anonymous   I placed a default aspx file in the directory and I received the following error      HTTP Error 500 21 - Internal Server   Error Handler    PageHandlerFactory-Integrated  has a   bad module  ManagedPipelineHandler  in   its module list   Are there any other steps I forgot to take to get this working   Notes  I installed IIS 7 5 after installing VS 2010 RC  I used the built-in  Create Virtual Directory  button under the  Web  tab in the MVC project s  Properties  in Visual Studio 2010  I made sure that the application is using the ASP NET 4 App Pool   Below are the installed features of IIS I have

If you re running IIS 8 5 on Windows 8  or Server 2012  you might find that running mvc 4 5   net 4 5  doesn t work in a virtual directory  If you create a local host entry in the host file to point back to your local machine and then point a new local IIS website to that folder  with the matching host header entry  you ll find it works then

ASP NET 4 was not registered in IIS  Had to run the following command in the command line run  32bit  x86  Windows      windir  Microsoft NET Framework v4 0 30319 aspnet regiis exe -ir   64bit  x64  Windows      windir  Microsoft NET Framework64 v4 0 30319 aspnet regiis exe -ir   Note from David Murdoch s comment       That the  net version has changed   since this Answer was posted  Check   which version of the framework is in   the  windir  Microsoft NET Framework64   directory and change the command   accordingly before running  it is   currently v4 0 30319

I had another problem that led to this issue    I had ensured my app pool was running  net 4 in integrated mode I had run aspnet regiis exe -i I had checked folder permissions were set correctly for the account running my app pool   None of these things worked   It turned out that in my web config under system webserver   modules I had the following    lt remove name  WindowsAuthentication    gt    Obviously this removed the windows authentication module which seemed to somehow knock everything off kilter   I hope this helps someone  as this cost me most of an evening

One more thing to make sure you have is the following set in your web config    lt system webServer gt       lt modules runAllManagedModulesForAllRequests  true   gt    lt  system webServer gt

Another possible solution  if you move around your global asax  make sure the markup points to the correct MvcApplication class  Hopefully this will save someone in future

I was also receiving this error and discovered that  HTTP Redirection  was not turned on in Windows Server  This blog post points this out as well  http   blogs msdn com b rjacobs archive 2010 06 30 system-web-routing-routetable-not-working-with-iis aspx

User · Answer

In my case ASP NET 4 5 is not installed on the server so installing ASP NET 4 5 fixed the issue

Adding another solution for this issue   in my Global asax cs file I had disabled attempted php files from being consumed by the MVC pipeline using the following   routes IgnoreRoute     php       I had done these previously in a MVC2 project and it worked fine  but doing this in my MVC 3 app caused the issue reported above

You can solve this error by running cmd as admin than    Do the same as in picture  for windows 32 bit  Just make changes in 64 bit as framework64 instead of framework only Than go to iis and refresh the site If u still got some error make changes in application pool

As strange as it may seem  reinstalling IIS was what has worked for me  with the following command run from inside the  net version folder   aspnet regiis exe  i     When I first run this command  I begun getting the HTTP Error 403 14  But once I runned the command again it solved the problem   Obs  Another thing I also did was to remove HTTP Redirect from the server features in Server Management screen before reiinstalling IIS  Maybe this also had an impact in solving the problem  but I am not sure  So  if reinstalling IIS still doesn t work  please try removing HTTP Redirect and try again  Hopefully it may work for you too

The UI is a bit different in the newer versions of Windows Server  Here is where you have to enable ASP Net in order to get it working on IIS

I created a new namespace  and therefore folder  identical to the route to a controller  e g  MvcApp Test SomeClasses cs and MvcApp Controllers TestController cs   This resulted also in a 403 14

This worked for me and it might be useful to another one   Maybe all components required are not present or and not all are registered correctly  In order to solve this  try to uncheck all options inside Control Panel -  Turn Windows features on or off -  Internet Information Services -  World Wide Web Services -  Application Development Features    uncheck all options and recheck all then reset the IIS and check if the problem is solved

Make sure you have is the following set in your web config    lt system webServer gt       lt modules runAllManagedModulesForAllRequests  true   gt    lt  system webServer gt    Better solution   Even though above solution works absolutely fine  it can cause other problem as it runs all your registered HTTP modules on every request  even on every request of  jpg  gif  css  html  pdf etc  and it is obviously waste of resource  Instead    lt system webServer gt   lt modules gt     lt remove name  UrlRoutingModule-4 0   gt     lt add name  UrlRoutingModule-4 0  type  System Web Routing UrlRoutingModule  System Web  Version 4 0 0 0  Culture neutral  PublicKeyToken b03f5f7f11d50a3a  preCondition      gt   lt  modules gt   lt  system webServer gt    Make sure preCondition attribute is empty means it will run on all requests   Read more  http   www britishdeveloper co uk 2010 06 dont-use-modules-runallmanagedmodulesfo html  Read original post

Please note for Windows 8 users you need to add remove windows components and remove the version of  net reboot then re-install in order to register it with IIS  I presume this happens if you get  net 4 5 from visual studio and install IIS afterwards

Yet another reason this can happen - your RouteConfig cs or WebApiConfig cs are invalid   In my case  I had a route defined as such  note the parenthesis instead of curly brace        routeTemplate   api  something

We had a MVC application moved to a new server   NET 4 and MVC 3 was installed  but we still got    Error 403 14   In this case  this meant that IIS did not understand that it was dealing with a MVC application  it was looking for the default page   The solution was simple  HTTP Redirection was not installed on the server   Server Manager     Roles     Web Server  IIS      Roles Services     HTTP Redirection  Not installed  Installed it  problem solved

Sweet Jesus  I tried all of the above things  but found my settings identical   YET ANOTHER SOLUTION if you are having issues   http   support microsoft com kb 980368  Try installing this KB for your system  If you are seeing 404s it might be because you don t have this update -- and the isapi module just isn t getting found and there s not a lot you can do about that without this

I had used the WebDeploy IIS Extension to import my websites from IIS6 to IIS7 5  so all of the IIS settings were exactly as they had been in the production environment   After trying all the solutions provided here  none of which worked for me  I simply had to change the App Pool setting for the website from Classic to Integrated

To solve this problem without having to resort to 32 bit mode you will have to update the source code for this project  public static void RegisterUrlRoutesFromAttributes RouteCollection routes           Enumerate assembly for UrlRoute attributes      List lt MapRouteParams gt  routeParams   new List lt MapRouteParams gt         AppDomain CurrentDomain GetAssemblies            ToList            ForEach assembly   gt  routeParams AddRange GetRouteParamsFromAttributes assembly       I have raised this issue as a discussion on the discussion board at the IT cloud codeplex project   http   itcloud codeplex com discussions 262000
