I have a project which I have upgraded to .Net 4.0, but when I try to access it, I retrieve the following error:
HTTP Error 404.2 - Not Found
The page you requested could not be displayed because of the settings for the list of ISAPI and CGI restrictions on web server.
ErrorCode: 0x800704ec
Handler PageHandlerFactory-ISAPI-4.0_32bit
Do I need to do something extra to the IIS 7 or APP pool, when converting an existing site to a .NET 4.0 site?
Also if I look at ISAPI both 32bit and 64bit of the .Net 4.0 is installed.
In IIS, enable .NET 4.
Here is image:
I take it you're running on IIS6 right now..
Open the IIS manager, and go to the Web Service Extensions area.. You'll be able to enable .NET 4 in there.. All new extensions are disabled by default :)
If you're running on IIS7, .NET might not have registered in IIS.. Then open up an admin command prompt and navigate to the .NET 4 framework folder (C:\Windows\Microsoft.NET\Framework\v4.{version}). If you're on a 64 bit machine go to the Framework64 folder instead of the Framework folder.
Then run aspnet_regiis -i in there
I had this same issue. Strangely, for me it would run in integrated mode but not in classic mode for .NET 4. After enabling the .NET 4 extensions via the Isapi and Cgi restrictions section in IIS 7, it then began working in both modes. The Isapi and Cgi restrictions section is located at the server level node in IIS manager. This option should not be confused with the Isapi Filters section at the site level.

I am familiar with .Net in general but new to ASP.Net Core. I just had my first "self-hosted" ASP.Net Core MVC app running (created using templet and runs under Kestrel by default) . What I would like to do now it to host it in-process with IIS. But what I am struggling with is that I couldn't seem to find a clear and detailed instruction/document about what I need to do to get it to work. I have tried various configuration changes on my own but nothing works so far. I am running .Net Core 3.1 and using VS.Net 2019 on my Windows 10 environment. If someone could point me to the right direction it would be highly appreciated.
As far as I know, if you want to host the asp.net core application on the IIS. You should make sure you have installed the right hosting bundle.
Notice: No matter you use in-process or out-of-process, you all need install the IIS hosting bundle.
More details about how to install it, you could refer to this link.
After install the link, you could check your IIS module to make sure you have installed the right asp.net core module.
Then you could use VS to publish the application to right folder and create the IIS web site as below:

I am new to the world of IIS and I wanted to know the following...
I have heard about IIS Express. I run Windows 7 Ultimate and have installed the IIS that comes packaged with Windows 7.
As a developer, is there any major benefit for me if I install IIS Express over the default IIS that comes with Windows 7 for .Net Web projects?
Here are the differences from http://www.mywindowsclub.com/resources/3302-Key-differences-between-IIS-IIS-Developer.aspx.
If you already have IIS installed - its a better product. IIS express would only be used by people who don't have access to IIS or want something that is lighter than IIS but more like IIS than Cassini.
Integrated with OS
IIS 7 ships with the operating system and is tightly integrated to Windows.
IIS developer express is a separate downloadable tool
Targetted users
IIS 7 is for both developers as well as for production purposes.
IIS developer express can be used only for development purposes and not for production.
Supported Windows editions
IIS 7 will work only on Windows Vista and newer editions of Windows. In case of server OS, IIS 7 will work only on Windows 2008.
IIS developer edition will work even on older version - starting from Windows XP and newer.
Process model and activation
In IIS 7, the worker thread is automatically launched and managed by Windows Process Activation Service.
In case of IIS Express, user has to handle this.
FTP support
IIS developer express does not support FTP while IIS 7 supports it.
WCF support
IIS Developer express supports only WCF over HTTP.
IIS 7 supports WCF including over TCP, Named Pipes, and MSMQ.
Multi developer support
IIS 7 is a single user application.
IIS Developer express supports multi developer environment. Configuration files, settings, and Web content are maintained on a per-user basis.
Visual Studio integration
All editions and versions of Visual Studio have built-in support for IIS 7.
Only VS 2010 and future versions will have built-in support for IIS developer express.
Runtime extensions
IIS developer has support for URL Rewrite and FastCGI.
Webmatrix offers support for SEO, database management and Web Deployment. Other extensions that are offered with IIS are not yet tested with IIS Developer express.
Management Tools
IIS 7 is managed using the IIS Manager.
IIS Developer express can be managed using Webmatrix. Also, the express edition has support through system tray.
Port used by IIS
The default website comes with IIS 7 listens to port 80.
The default website part of IIS developer express listens to port 8080 to avoid conflicts with IIS 7 when they are running side by side.
From Scott Gu's post on IIS Express:
Why Not IIS
The downside with using the IIS option today, though, is that some
companies don’t allow full web-servers to be installed on developer
machines. IIS also requires administrator account access to setup and
debug projects. Different versions of Windows also support different
versions of IIS. For example, if you are running on Windows XP you
have to use the IIS 5.1 web-server that comes with it – which doesn’t
support all the new features of IIS 7.x. Configuring a web project
within VS to use IIS also requires some extra installation and
configuration steps.
Why IIS Express
It’s lightweight and easy to install (less than 10Mb download and a
super quick install) It does not require an administrator account to
run/debug applications from Visual Studio It enables a full web-server
feature set – including SSL, URL Rewrite, Media Support, and all other
IIS 7.x modules It supports and enables the same extensibility model
and web.config file settings that IIS 7.x support It can be installed
side-by-side with the full IIS web server as well as the ASP.NET
Development Server (they do not conflict at all) It works on Windows
XP and higher operating systems – giving you a full IIS 7.x developer
feature-set on all OS platforms IIS Express (like the ASP.NET
Development Server) can be quickly launched to run a site from a
directory on disk. It does not require any registration/configuration
steps. This makes it really easy to launch and run for development
scenarios.
After a couple of hours i found one significant reason to use Express over Local IIS : "Edit and Continue" does not work on local IIS.
I'm using IIS 7.5 on Windows Server 2008 R2 x64 Enterprise Edition. In the project we have developed with ASP.NET 4.0 we used WCF Service. But it doesn't run over domain when the software is running from local computer. Otherwise, I am getting the following error:
HTTP Error 404.3-Not Found
The page you are requesting cannot be served because of the extension
configuration. If the page is script, add a handler. If the file should
be downloaded, add a MIME map.
You should install IIS sub components from
Control Panel -> Programs and Features -> Turn Windows features on or off
Internet Information Services has subsection World Wide Web Services / Application Development Features
There you must check ASP.NET (.NET Extensibility, ISAPI Extensions, ISAPI Filters will be selected automatically). Double check that specific versions are checked. Under Windows Server 2012 R2, these options are split into 4 & 4.5.
Run from cmd:
%windir%\Microsoft.NET\Framework64\v4.0.30319\aspnet_regiis.exe -ir
Finally check in IIS manager, that your application uses application pool with .NET framework version v4.0.
Also, look at this answer.
In my case, along with Mekanik's suggestions, I was receiving this error in Windows Server 2012 and I had to tick "HTTP Activation" in "Add Role Services".
In windows server 2012, even after installing asp.net you might run into this issue.
Check for "Http activation" feature. This feature is present under Web services as well.
Make sure you add the above and everything should be awesome for you !!!
I was having trouble accessing wcf service hosted locally in IIS. Running aspnet_regiis.exe -i wasn't working.
However, I fortunately came across the following:
Rahul's blog
which informs that servicemodelreg also needs to be run:
Run Visual Studio 2008 Command Prompt as “Administrator”.
Navigate to C:\Windows\Microsoft.NET\Framework\v3.0\Windows Communication Foundation.
Run this command servicemodelreg –i.
I need to register a custom isapi extension on my web server, but I can't seem to find the option on my IIS 7.5/Win7 (pro) box.
On IIS 6 it used to be under "Home Directory" -> Configuration -> Wildcard application maps.
How can I achieve the same on IIS 7.5?

See article Developing IIS 7.0 Modules and Handlers with the .NET Framework and go at "Deploying the Assembly to the Server"
I have a web-page application already created, but when I open it in visual studio 2008, it says there that:
ASP.NET 2.0 has not been registered on the Web Server. You need to
manually configure you Web server for ASP.NET 2.0 in order for your
site to run correctly.
I'm using asp.net 2.0, IIS7 and running on vista home premium.
How to register ASP.NET 2.0 to my web server(IIS7)?
ASP .NET 2.0:
C:\Windows\Microsoft.NET\Framework\v2.0.50727\aspnet_regiis.exe -ir
ASP .NET 4.0:
C:\Windows\Microsoft.NET\Framework\v4.0.30319\aspnet_regiis.exe -ir
Run Command Prompt as Administrator to avoid the ...requested operation requires elevation error
aspnet_regiis.exe should no longer be used with IIS7 to install ASP.NET
Open Control Panel
Programs\Turn Windows Features on or off
Internet Information Services
World Wide Web Services
Application development Features
ASP.Net <== check mark here
If anyone like me is still unable to register ASP.NET with IIS.
You just need to run these three commands one by one in command prompt
cd c:\windows\Microsoft.Net\Framework\v2.0.50727
after that, Run
aspnet_regiis.exe -i -enable
and Finally Reset IIS
iisreset
Hope it helps the person in need... cheers!
If you installed IIS after the .Net framework you can solve the porblem by re-installing the .Net framework. Part of its install detects whether IIS is present and updates IIS accordingly.
Open Control Panel
- Programs
- Turn Windows Features on or off
expand - Internet Information Services
expand - World Wide Web Services
expand - Application development Features
check - ASP.Net
Its advisable you check other feature to avoid future problem that might not give direct error messages

The system I was working on is Windows Server 2008 Standard with IIS 7 (I guess that my experience will apply for all Windows systems of the same age).
Running
C:\Windows\Microsoft.NET\Framework\v4.0.30319\aspnet_regiis.exe -ir
SEEMED to work, as
C:\Windows\Microsoft.NET\Framework\v4.0.30319\aspnet_regiis.exe -lv
showed the .Net framework v4 registered with IIS.
But, running the same for .Net v2, namely
C:\Windows\Microsoft.NET\Framework\v2.0.50727\aspnet_regiis.exe -ir
did NOT result in
C:\Windows\Microsoft.NET\Framework\v2.0.50727\aspnet_regiis.exe -lv
showing the framework registered.
(And, for me, the installer for Kofax Capture Network Server was still missing ASP.NET.)
The solution was:
Open Server Manager
Go to Roles/Web Server (IIS)
Push Add Role Services
check ASP.NET under Application Development (and press Install)
After that, aspnet_regiis.exe -lv (either version) shows the framework registered.
(And the Kofax installer was also happy and worked.)
I got it resolved by doing Repir on .NET framework Extended, in Add/Remove program ;
Using win2008R2, .NET framework 4.0
