I am in the process of converting out web site project to a web application project. I've got everything to compile and even publish (long process). However, now that I've got the project "loading" in IIS, the httpModule is not called.
The modules section of web.config looks like this:
<modules runAllManagedModulesForAllRequests="true">
<add name="ContentWebSite" type="ContentWebSite.ContentWebSite"/>
</modules>
the class of the httpModule starts like this:
namespace ContentWebSite
{
public class ContentWebSite : IHttpModule
{
private HttpApplication _Application;
What am I missing? Setting a breakpoint in the constructor or the init method of the ContentWebSite class is never hit when I'm running in the context of local IIS. When I run in IIS Express, the breakpoint is hit! How do I get IIS to invoke the httpModule?
TIA,
You can check if the application pool mode caused your problem.
Application pool mode: classic versus integrated.
<system.webServer><!--for integrated mode-->
<modules>
<add name="modulename" type="ContentWebSite.ContentWebSite" />
</modules>
</system.webServer>
<system.web><!--for classic mode-->
<httpModules>
<add name="modulename" type="ContentWebSite.ContentWebSite" />
</httpModules>
</system.web>
OK, so I got this working by changing the modules add name line to this:
<add name="modulename" type="ContentWEbSite.ContentWebsite, appName" />
Where appName is the physical name of the DLL generated for the project!
I use IIS 10 on windows 10, I was use to have web.config files with customErrors, but now it is not accepting it anymore. I been procrastinating hotfixing just removing the line from the webconfig, but now I am trying to figure out what is wrong and fix it once and for all.
Error Source:
<system.web>
<customErrors mode="Off"/>
<httpRuntime targetFramework="4.6.2" />
The machine config has <deployment retail="true" />, and whit this configuration if I remove the tag IIS works fine and the web application is served correctly, if I change the retail setting to false, it will break again asking for the customErrors to be set.
I could not find any information online on this specific type of issue, and I tried to follow also the error code investigation path, but it leads to TLS configuration which in my case is correct and enabled.
After lots of digging I found that one of the machine.config (for the current framework4x and architecture x64) had a missing section in the system.web group:
<sectionGroup name="system.web" type="System.Web.Configuration.SystemWebSectionGroup, System.Web, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a">
<section name="customErrors" type="System.Web.Configuration.CustomErrorsSection, System.Web, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" />
I copied the section from the 32 bit version of the machine.config and this fixed the issue.
This documentation about IIS configuration hierarchy helped me:
https://learn.microsoft.com/en-us/iis/get-started/planning-your-iis-architecture/the-configuration-system-in-iis-7#:~:text=%20At%20the%20root%20%28or%20global%29%20level%2C%20there,global%20defaults%20for%20the%20.NET%20framework...%20More%20
I'm setting up the first site in IIS on Windows Server 2016 Standard.
This is a NET Core 2.2 application. I cannot get the site to show.
I am getting this error:
HTTP Error 500.0 - ANCM In-Process Handler Load Failure
What can I change to clear this error and get my site to display?
My application is a dll.
I tested my application on the server through the Command Prompt with
dotnet ./MyApp.dll
it displays in the browser but only on the server itself with (localhost:5001/).
Using this method the site cannot be accessed from any other server.
When I set up the site through IIS, I get the In-Process error both on the server and from servers attempting to access the site.
At first I was receiving the Out-Process error. Something I read said to add this (hostingModel="inprocess") to my web.config
so I did but now I receive the In-Process error.
The site works fine when installed on my development server.
The Event Viewer shows this error for "IIS AspNetCore Module V2":
Failed to start application '/LM/W3SVC/2/ROOT', ErrorCode '0x8000ffff'.
This is my web.config:
<?xml version="1.0" encoding="utf-8"?>
<configuration>
<system.web>
<customErrors mode="RemoteOnly"></customErrors>
<identity impersonate="false" password="****" userName="****" />
</system.web>
<system.webServer>
<handlers>
<add name="aspNetCore" path="*" verb="*" modules="AspNetCoreModuleV2" resourceType="Unspecified" />
</handlers>
<aspNetCore processPath="dotnet" arguments=".\MyApp.dll" stdoutLogEnabled="false" hostingModel="inprocess" stdoutLogFile=".\logs\stdout" forwardWindowsAuthToken="false">
<environmentVariables />
</aspNetCore>
</system.webServer>
</configuration>
I had the same issue in .Net core 2.2. When I replace
web.config:
<handlers>
<add name="aspNetCore" path="*" verb="*" modules="AspNetCoreModuleV2" resourceType="Unspecified" />
</handlers>
to
<handlers>
<add name="aspNetCore" path="*" verb="*" modules="AspNetCoreModule" resourceType="Unspecified" />
</handlers>
then it works fine.
Note: The same solution also works for .Net core 2.2 and other upper versions as well.
Open the .csproj file and under Project > PropertyGroup > AspNetCoreHostingModel, change the value “InProcess” to “OutOfProcess”.
<PropertyGroup>
<TargetFramework>netcoreapp2.2</TargetFramework>
<AspNetCoreHostingModel>OutOfProcess</AspNetCoreHostingModel>
Sometimes this is because multiple applications may be using same Application Pool
In such cases first application will work and other won't work
Solution is to create new application pool for each application.
I had the same error.
According to Microsoft(https://dotnet.microsoft.com/download/dotnet-core/current/runtime), We should install the 'ASP.NET Core Hosting Bundle' in our hosting server.
'The ASP.NET Core Hosting Bundle includes the .NET Core runtime and ASP.NET Core runtime. If installed on a machine with IIS it will also add the ASP.NET Core IIS Module'
After I did, The 'AspNetCoreModuleV2' installed on my server and everything works well. It didn't need to change your 'web.config' file.
For more info, in web.config, set
stdoutLogEnabled="true"
then check the logs folder. In my case it had nothing to do with project, publishing or hosting settings - it was my fault for not copying a file essential to my app. The error was simply "Could not find file "D:\Development\IIS Hosting Test\filename.ext"
For my particular issue it was the site permissions in IIS.
I edited the permissions to "Everyone" and it worked. I got the information from this page: https://github.com/aspnet/AspNetCore/issues/6111
I belive that IISExpress got messed up along the way.
Try the following:
'Clean Solution' from VS
Got to the solution folder and delete the .vs folder from there.
Build and run.
I faced with the same issue today, installing the following package on server is fixed the issue for me. If you have any previous version of Windows Hosting Bundle already installed on the server, you install the new one without restarting the server.
ASP.NET Core 3.1 Runtime (v3.1.11) - Windows Hosting Bundle
In my case updating .net core sdk works fine.
You can get this if you try to access the site using a IIS url but Visual Studio is setup to use IISExpress
See also
ASP.Net Core 1.0 RC2 : What are LAUNCHER_PATH and LAUNCHER_ARGS mentioned in web.config?
Long story short, the web.config is changed by Visual Studio when you switch between IIS and IISExpress. If you use an IIS url when it's setup to use IISExpress then the aspNetCore processPath will be wrong
Also, it's not uncommon to copy web.config files. You could get the same error if you don't change the processPath
I fixed this here Asp.Net Core Fails To Load - you need to specify that the program uses an in process or out of process model.
I changed my CreateWebHostBuilder to:
public static IWebHostBuilder CreateWebHostBuilder(string[] args)
{
var env = Environment.GetEnvironmentVariable("ASPNETCORE_ENVIRONMENT");
var builder = WebHost.CreateDefaultBuilder(args);
if (env == EnvironmentName.Staging || env == EnvironmentName.Production)
builder.UseIIS();
builder.UseStartup<Startup>();
return builder;
}
PS. I set ASPNETCORE_ENVIRONMENT in my .pubxml deployment profile by adding:
<PropertyGroup>
<EnvironmentName>Staging</EnvironmentName>
</PropertyGroup>
For me it was because I had ASPNETCORE_ENVIRONMENT environment variable being defined 2 times in my app - one in web.config and another - in applicationhost.config
In my case just adding MVC into Startup.cs Please follow into image. I am trying to add dependency injection then showing this problem. I think it will be helpful.

Delete the 'hosting Model ="in process"' section in web config.
Example:
<aspNetCore processPath="dotnet" arguments=".\WebAPICore.dll" stdoutLogEnabled="false" stdoutLogFile=".\logs\stdout" hostingModel="inprocess" />
to
<aspNetCore processPath="dotnet" arguments=".\WebAPICore.dll" stdoutLogEnabled="false" stdoutLogFile=".\logs\stdout" />
I'm also getting "HTTP Error 500.0 - ANCM In-Process Handler Load Failure"
Except in my case...Everything was running great until I got the Blue Screen of Death.
I have a solution with two startup projects. One is an API (that comes up) and the other is a WebApp(which gets the error). Both are .NET Core 3.1..also VS2019.
First I tried setting a break point in Main() of program.cs...it never got this far.
public static void Main(string[] args)
{
CreateHostBuilder(args).Build().Run();
}
On a hunch...I Looked at the NuGet packages installed.
I uninstalled and (re)installed
Microsoft.AspNetCore.Mvc.Razor.RuntimeCompilation(3.1.6)
...and now its working again.
In case anyone else cannot find a solution to this here was my scenario:
I recently started a new project using .NET 5, and everything was working. Then I upgraded from Preview 5 to 7 and all of a sudden my IIS Express would no longer work. The fix for me was to simply repair Visual Studio:
.
This happened to me when I switched form debugging in IIS Express to IIS. I inspected Event Viewer > Application log, and found the following error there:
Executable was not found at '...\bin\Debug\netcoreapp3.1\%LAUNCHER_PATH%.exe'
I then found the solution to that in the following thread.
I basically needed to replace web.config entry with hard-coded name of the application:
<aspNetCore processPath="dotnet" arguments=".\ProjectName.dll" stdoutLogEnabled="false" stdoutLogFile=".\logs\stdout" forwardWindowsAuthToken="false"/>
I get that error when i try to get data from the ViewModel as List<> and my data is coming as IEnumerable format.
Before u guys update your vs2019 or delete some files,u should better to check it out that option.
For me it was caused by different web.config files for development and deployment :
development: <aspNetCore requestTimeout="23:00:00" processPath="%LAUNCHER_PATH%" arguments="%LAUNCHER_ARGS%" forwardWindowsAuthToken="false" stdoutLogEnabled="true" stdoutLogFile=".\logs\stdout" startupTimeLimit="3600" hostingModel="InProcess">
deployment : <aspNetCore requestTimeout="23:00:00" processPath=".\Nop.Web.exe" arguments="" forwardWindowsAuthToken="false" stdoutLogEnabled="false" stdoutLogFile=".\logs\stdout" startupTimeLimit="3600" hostingModel="InProcess">
In my case, I put app_name.exe back from my backup folder to bin\debug, and boom it worked.
If you don't have a backup folder that contains exe so don't worry publish your web app / web API and copy from there
No previous answers worked for me. In my case the "processPath" inside "aspNetCore" tag was pointing to a non-existing folder. A colleague told me that when any value in the web.config is wrong the app doesn't start and emerge this weird error.
In my case, after updating to .Net 6 and using a self contained application I started seeing this error.
I could manually set the module to AspNetCoreModule and the application would run in IIS but I knew this was just a work around since AspNetCoreModuleV2 should be used with .Net 6 applications
I had the following line in the ConfigureServices method:
services.AddMvc().SetCompatibilityVersion(CompatibilityVersion.Version_3_0);
Removing the compatibility version resolved my issue.
services.AddMvc();
This is a temporary problem caused by changes in folder or host settings while the application was running.
Most solutions provided here are working because they are indirectly triggering a restart. eg: Changing web.config will trigger a process cleanup and restart for that app.
Solution: Is restart the application process
If the problem still persist after the restart then check EventViewer to see the actual problem, a persistent problem usually means your application has a bug.
I tried changing aspnetCoreModuleV2 to aspnetCoreModuleV2, which worked, but it was a hassle to change every time I published it in Visual Studio.
After testing, I found that I could change the application pool default Settings for IIS to enable 32-bit applications in general.
But I haven't tested it on a 32-bit computer, it should be OK.
See Screenshot.
Fixing all project build errors, would simply fix this issue & the application will load.
Change platform target to Any CPU.
I just moved a website and related web service from IIS6 to 8.
The website works fine, but the webservice is giving the following error:
Server Error in '/CreditCardService' Application.
Could not load file or assembly 'System.Web.Mvc, Version=3.0.0.1, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The system cannot find the file specified.
The web service config file do not have any related lines in it.
Only the website web.config has any related lines in it, see below.
<add assembly="System.Web.Mvc, Version=3.0.0.1, Culture=neutral, PublicKeyToken=31BF3856AD364E35" />
Any ideas how to resolve this?
I have a pretty standard Sitecore site (no extra assemblies etc., just some layouts and xslt files). The site is working fine on my own server (old w2003 w/iis6). The site now needs to be moved to a new server (w2008 w/iis7). But the site fails to lad, giving this error;
Could not load file or assembly 'System.Web.Helpers, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The system cannot find the file specified.
In the following line in the web.config
Line 3176: <add assembly="System.Web.Helpers, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" />
Any ideas as to what could be wrong? I dont have access to the server myself, but have just been sent a link to the site, where i can see the above error.
It seems that you have MVC dependencies you also have to deploy to a new server. This thread might be helpful.
