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.
Follow this Image: https://i.stack.imgur.com/ykw8P.png
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 have Windows 2008 R2 Server with IIS 7.5.
I am trying to serve static files with non-English (Hebrew) names, but cannot get it working.
I have 4 files:
a.jpg
א.jpg
b.txt
ב.txt
When I try to go to http://.../a.jpg and http://.../b.txt, I am getting the right files.
But when I try to access http://.../א.jpg or http://.../ב.txt it won't work.
Even if I encode the file names before going to url i.e http://../%D7%90.jpg it won't work as well.
I am getting a regular 404 server error:
404 - File or directory not found.
The resource you are looking for might have been removed, had its name changed, or is temporarily unavailable.
I tried the following, but it didin't help:
1.adding globalization settings to web.config:
<configuration>
<system.web>
<globalization
fileEncoding="utf-8"
requestEncoding="utf-8"
responseEncoding="utf-8"
/>
</system.web>
</configuration>
2.adding .jpg and .txt to MIME Types settings in IIS.
What am I missing here?
I found a solution to this problem.
It was all about UrlScan IIS extension...
All I had to do is:
Go to the UrlScan folder inside windir%\system32\inetsrv [32bit] and %windir%\syswow64\inetsrv [64bit]
Open UrlScan.ini and change AllowHighBitCharacters to 1
I am working on a Unity 3D game which upon build for Windows generates game.exe and game_Data file and folder. The Game_Data folder contains a directory called **Game_Data\Mono\etc\mono\2.0**.
The directory files are shown in image.
The Browsers directory contains one file called Compact.browser.
The Current Scenario.
1. These game files are hosted on a server where IIS 7.5 is running.
The game resource files are served in virtual directory of the game website.
I've made few changes to the website's root web.config file so that all filetypes are allowed to download only in the game resources folder on server.
Yes, all file types including .html, .aspx, .xml, .config, .browser, .map etc are all downloading as normal files.
The problem
As you see the directory structure there is a web.config file inside the game resources folder. The file has nothing to do with website configuration but with the game (which is on client side after downloading).
As the files are served as individual files each file is downloaded separately. So when the client tries to download all files including the contents of the above folder.
Due to this web.config file, contents of the directory is not downloading. If I delete this web.config file all of the .aspx, .config, .map files are downloading. Also there are some other folders where many different files are downloading properly.
But this web.config file is also required for the game, and it is not allowing it be downloaded with other files too in the directory shown above.
I've tried to look into the solution. Found some hints to avoid inheritance in nested config files. But actually I want to completely treat this file as a normal file, not as a site configuration file.
I think you got my problem. Please let me know your suggestions. You can say adding Mime types. But actuall all of the file types are downloading including .config files. Except the file named web.config.
I'm having the same problem, and I think I found the solution: there is a way to tell IIS not to interpret web.config files.
To do this, modify the C:\Windows\System32\inetsrv\config\applicationHost.config file (I haven't found a way to do this in the IIS user interface), by specifying allowSubDirConfig="false" for the relevant <virtualDirectory> element:
<configuration>
<system.applicationHost>
<!-- ... -->
<sites>
<site name="Default Web Site" id="1">
<application path="/">
<virtualDirectory path="/" physicalPath="%SystemDrive%\inetpub\wwwroot" />
<virtualDirectory path="/Staging" physicalPath="C:\inetpub\wwwroot\Staging" allowSubDirConfig="false" />
</application>
<bindings> <!-- ... --> </bindings>
</site>
See http://www.iis.net/configreference/system.applicationhost/sites/site/application/virtualdirectory for the details.
The problem is, it still won't let you download the web.config file, it keeps returning a 404 - Not found, even after removing all handlers.
Edit - found the solution. The short answer is that in your web.config, you should clear the fileExtensions and hiddenSegments lists:
<system.webServer>
<security>
<requestFiltering>
<hiddenSegments>
<clear />
</hiddenSegments>
<fileExtensions>
<clear />
</fileExtensions>
</requestFiltering>
</security>
I've written a blog article about it that explains all the details.
I have the problem, that the IIS from Visual Studio Express 2013 for Web doesn't allow the loading of *.json files. When trying to load a *.json file I get a 403 Forbidden and a help page how to configure the IIS allow the loading of JSON files, but don't know what to do with this information / where the IIS is even located.
This is the error page:
HTTP Error 404.3 - Not Found The page you are requesting cannot be
served because of the extension configuration. If the page is a
script, add a handler. If the file should be downloaded, add a MIME
map.
Most likely causes: It is possible that a handler mapping is missing.
By default, the static file handler processes all content. The feature
you are trying to use may not be installed. The appropriate MIME map
is not enabled for the Web site or application. (Warning: Do not
create a MIME map for content that users should not download, such as
.ASPX pages or .config files.) If ASP.NET is not installed.
Things you can try: In system.webServer/handlers: Ensure that the
expected handler for the current page is mapped. Pay extra attention
to preconditions (for example, runtimeVersion, pipelineMode, bitness)
and compare them to the settings for your application pool. Pay extra
attention to typographical errors in the expected handler line. Please
verify that the feature you are trying to use is installed. Verify
that the MIME map is enabled or add the MIME map for the Web site
using the command-line tool appcmd.exe. To set a MIME type, run the
following command in the IIS Express install directory: appcmd set
config /section:staticContent
/+[fileExtension='string',mimeType='string'] The variable
fileExtension string is the file name extension and the variable
mimeType string is the file type description. For example, to add a
MIME map for a file which has the extension ".xyz": appcmd set config
/section:staticContent /+[fileExtension='.xyz',mimeType='text/plain']
Warning: Ensure that this MIME mapping is needed for your Web server
before adding it to the list. Configuration files such as .CONFIG or
dynamic scripting pages such as .ASP or .ASPX, should not be
downloaded directly and should always be processed through a handler.
Other files such as database files or those used to store
configuration, like .XML or .MDF, are sometimes used to store
configuration information. Determine if clients can download these
file types before enabling them. Install ASP.NET. Check the failed
request tracing logs for additional information about this error. For
more information, click here.

After some more googling, and experimenting I found out, that you have to define IIS settings in the Web.config.
After adding the following configuration:
<system.webServer>
<staticContent>
<mimeMap fileExtension=".json" mimeType="application/json" />
</staticContent>
</system.webServer>
it works like a charm.
Full setup file example:
<?xml version="1.0"?>
<configuration>
<system.web>
<compilation debug="true" targetFramework="4.0"/>
</system.web>
<system.webServer>
<staticContent>
<mimeMap fileExtension=".json" mimeType="application/json" />
</staticContent>
</system.webServer>
</configuration>
Better add remove tag in case future IIS has build in json support. This is my web.config section of mimeMap.
<system.webServer>
<staticContent>
<remove fileExtension=".woff" />
<remove fileExtension=".woff2" />
<remove fileExtension=".json" />
<mimeMap fileExtension=".woff" mimeType="application/x-font-woff" />
<mimeMap fileExtension=".woff2" mimeType="application/font-woff2" />
<mimeMap fileExtension=".json" mimeType="application/json" />
</staticContent>
<system.webServer>
Open CMD with administrator privilages.
Go to:
cd C:\Program Files\IIS Express
or
cd C:\Program Files (x86)\IIS Express
Run command:
appcmd set config /section:staticContent /+[fileExtension='JSON',mimeType='application/x-javascript']
We may need to distinguish the Visual Studio development environment (with IIS Express) from local IIS and a remote server (like Azure WebSites). To specifically target IIS Express, for example, we edit %USERPROFILE%\Documents\IISExpress\config\applicationhost.config under system.webServer/staticContent:
<mimeMap fileExtension=".json" mimeType="application/javascript" />
I need to make this distinction because my local (intranet) IIS already has the JSON mime type defined. So when I deploy to Azure websites I use this transformation in Web.Release.config:
<system.webServer>
<staticContent>
<mimeMap fileExtension=".json" mimeType="application/javascript" xdt:Transform="Insert" />
</staticContent>
</system.webServer>
IISExpress writes log and configuration data to pre-determined location out of the box.
The directory is an "IISExpress" directory stored in a user's Documents directory.
In the directory is stored the following folders files underneath.
Config
Logs
TraceLogFiles
The location of my home directory is on a network share, determined by group policy
Currently we are encountering scenarios where visual studio locks up when stopping debugging Silverlight applications using IIS Express.
I was looking to change the location for the log & configuration data for IISExpress to see if this fixes the problem of visual studio locking up. Is it possible to change the default location of log & config files ?
1 . By default applicationhost.config file defines following two log file locations. Here IIS_USER_HOME would be expanded as %userprofile%\documents\IISExpress\.
<siteDefaults>
<logFile logFormat="W3C" directory="%IIS_USER_HOME%\Logs" />
<traceFailedRequestsLogging directory="%IIS_USER_HOME%\TraceLogFiles" enabled="true" />
</siteDefaults>
You can update above directory paths to change the log file locations.
2 . If you are running IIS Express from command line, you can use '/config' switch to provide configuration file of your choice. Following link may help you http://learn.iis.net/page.aspx/870/running-iis-express-from-the-command-line/
http://www.iis.net/configreference/system.applicationhost/sites/sitedefaults
<configuration>
<system.applicationHost>
<sites>
<siteDefaults>
<logFile
logFormat="W3C"
directory="%SystemDrive%\inetpub\logs\LogFiles"
enabled="true"
/>
<traceFailedRequestsLogging
enabled="true"
directory="%SystemDrive%\inetpub\logs\FailedReqLogFiles"
maxLogFiles="20"
/>
<limits connectionTimeout="00:01:00" />
<ftpServer serverAutoStart="true" />
<bindings>
<binding
protocol="http"
bindingInformation="127.0.0.1:8080:"
/>
</bindings>
</siteDefaults>
</sites>
</system.applicationHost>
</configuration>
I find web.config documentation is a messy. It is therefore better to provide a complete parent history than a floating snippet with the expectation that the reader naturally knows where it goes.
By default it will be in:
C:\Users\ user_name \Documents\IISExpress\Logs\
