I have a site on IIS server which hosts ASP.NET REST APIs. They work on separate application pools which all have Unmanaged Code as their .NET CLR version. All .NET Core APIs .NET Core 3.1 written.
I have also installed hosting bundle, SDK, ASp.NET And Desktop SDKs as shown below.
Unfortunately the app does not work. When I investigate it seems the error is IIS/configuration related. The application I have deployed is published as follows :
And the web.config is as follows :
<?xml version="1.0" encoding="utf-8"?>
<configuration>
<location path="." inheritInChildApplications="false">
<system.webServer>
<handlers>
<add name="aspNetCore" path="*" verb="*" modules="AspNetCoreModuleV2" resourceType="Unspecified" />
</handlers>
<!-- The line below -->
<aspNetCore processPath=".\Unity.REST.API.WM.exe" stdoutLogEnabled="true" stdoutLogFile=".\logs\stdout" hostingModel="inprocess" />
</system.webServer>
</location>
</configuration>
With this configuration, when I try to open Configuration Manager of the site under Management tab I get the following error.
However if I remove the line under the "The line below" comment, I can view configuration, but I certainly need to keep that line to make my .NET Core REST API working.
I have copied all the files and config from another server and it works OK there. Is there any possible solution you can suggest?
In applicationhost.config, check if you have such an entry:
<section name="aspNetCore" overrideModeDefault="Allow" />
Believe it should be under <configuration> -> <configSections> -> <sectionGroup name="system.webServer">
If you don't have it, try adding it and restart IIS.
This problem occurs because the ApplicationHost.config or Web.config file contains a malformed or unidentified XML element. IIS can't identify the XML elements of the modules that are not installed. You can find probloem element by commenting some blocks and looking for type of error.
And you can also try to check whether URL rewrite is installed.

I have published an ASP.NET Core application on IIS that won't work.
I followed these steps/tutorial: https://stackify.com/how-to-deploy-asp-net-core-to-iis/ and https://stackoverflow.com/a/646386/11498427
So this is my web.config:
<?xml version="1.0" encoding="utf-8"?>
<configuration>
<system.webServer>
<handlers>
<add name="aspNetCore" path="*" verb="*" modules="AspNetCoreModule" resourceType="Unspecified"/>
</handlers>
<aspNetCore processPath="%LAUNCHER_PATH%" arguments="%LAUNCHER_ARGS%" stdoutLogEnabled="false" stdoutLogFile=".\logs\stdout" forwardWindowsAuthToken="false"/>
</system.webServer>
</configuration>
Published the ASP.NET Core application with the file folder publish. Then unzipped it and put the whole folder inside: "C:\inetpub\wwwroot\"
Set the appropriate folder's with the full control permissions.
Set the appropriate authentication within IIS manager
Set the appropriate settings for the application pool.
.NET Core Server bundle correctly installed (latest, see screenshot)
'localhost' working fine. But whenever I try to reach my application it gives me a 404. Anyone knows what could be the problem? Thanks in advance.
Ok - this is my first deployment of an ASP.NET Core app. One wrinkle to keep in mind is that I am using ASP.NET Core 2.2 and targeting Framework version 4.6.2 (not .Net Core). It all runs fine on my local machine with VS2017 and IISExpress.
I went through the procedure outlined by MS here: Host ASP.NET Core on Windows with IIS The documentation is long and complicated, but I think I covered everything. It makes one thing clear: The in-process hosting model isn't supported for ASP.NET Core apps that target the .NET Framework. So, I know I need to use Out-of-Proc.
Some other points:
I published the app to a local folder and copied it to the server without any changes.
I created the new app in the Default Web Site and gave it its own app pool - set as "No Managed Code"
Out-of-proc is the default, so I have not done any special config for this.
I have confirmed that AspNetCoreModuleV2 appears in the list of Modules.
The Result
Every page I hit I get HTTP404. I am running IE locally on the server and using a URL like: http://localhost/MyApp/Home/MyView
The application pool shows having 1 application running.
The App Event Log shows a message like: Application '/LM/W3SVC/2/ROOT/MyApp' started process '8864' successfully and process '8864' is listening on port '37706'. It shows no errors.
I have tried adding a default.htm file to the root of the app and loading the static page directly (using http://localhost/MyApp/default.htm). This gives 404. If I remove the web.config, this page will load.
I really didn't expect deploying the app to be this complicated.
Can anyone provide any guidance on how to troubleshoot or fix this problem?
Update 1: Web.config is below. I have tried with and without hostModel=... aspNetCore logs show successful startup. Nothing is added to the log with each page access attempt (seems weird)
<?xml version="1.0" encoding="utf-8"?>
<configuration>

Solved! I was making use of the ASPNETCORE_ENVIRONMENT environment variable, but was unaware that the publish process does not put this in web.config. I added this to Web.config:
<environmentVariables>
<environmentVariable name="ASPNETCORE_ENVIRONMENT" value="Development" />
</environmentVariables>
and the pages now load.
The most useful diagnostics I found were at this link Troubleshoot ASP.NET Core on IIS There they recommended that I run My.App.Name.exe from the command prompt. This creates a web process and assigns it to a port and gives you all the console output. This allowed me to figure out it was actually half working and that led me to the fact that I was missing the Env Variable.
Thanks again for the suggestions...
I'm attempting to host a ASP.NET 2.2 Website on a interserver.com shared hosting platform. They are using Plesk Onyx version 17.8.11 as their hosting platform control panel.
I've verified the hosting is routed and setup correctly but still get the runtime error:
HTTP Error 500.0 - ANCM In-Process Handler Load Failure
The specified version of Microsoft.NetCore.App or Microsoft.AspNetCore.App was not found
The in process request handler, Microsoft.AspNetCore.Server.IIS, was not referenced in the application
ANCM could not find dotnet.
I reported the issue to customer service and they have sent me a few articles of things to try but no solution has been found. Since the error says that the key aspnet core library could not be found, they said they have "installed .NET core 2.1.10 and 2.2.2 hosting bundle" but I'm still getting the same error.
The web.config on the host (auto-generated) is:
<?xml version="1.0" encoding="utf-8"?>
<configuration>
<location path="." inheritInChildApplications="false">
<system.webServer>
<handlers>
<add name="aspNetCore" path="*" verb="*" modules="AspNetCoreModuleV2" resourceType="Unspecified" />
</handlers>
<aspNetCore processPath="dotnet" arguments=".\BridgeSite.dll" stdoutLogEnabled="false" stdoutLogFile=".\logs\stdout" hostingModel="InProcess" />

Any suggestions stackoverflow family?
Since this is a shared hosting platform I do not have access to fiddle around with server configurations. From what I can tell, something went wrong with the ASP.NET Core 2.2.4 runtime installation and AspNetCoreModuleV2.dll is missing/corrupt/misplaced?
After spending far to much time on this I found a couple workarounds:
Every time you publish, go to the folder on the host where the code was published, open the auto-generated web.config, under the handlers node replace "AspNetCoreModuleV2" with "AspNetCoreModule". This works, by defaulting it back to the previous package, but is crappy because it has to be done manually every time the code is published.
OR,
in the Visual Studio solution, open (or create new) publish profile under Properties > PublishProfiles. In the PropertyGroup add: <AspNetCoreHostingModel>OutOfProcess</AspNetCoreHostingModel>. This works but is a big hack and the application will not have all the performance gains of being InProcess (Default)
After testing, I found you can use one or the other, you don't have to use both.
I'm hoping this issue will resolve itself over time as the hosting service continues to update their runtimes, but for now hopefully those workarounds will help you too.
This error is documented, along with the solution:
500.0 In-Process Handler Load Failure
The worker process fails. The app doesn't start.
The ASP.NET Core Module fails to find the .NET Core CLR and find the in-process request handler (aspnetcorev2_inprocess.dll). Check that:
The app targets either the Microsoft.AspNetCore.Server.IIS NuGet package or the Microsoft.AspNetCore.App metapackage.
The version of the ASP.NET Core shared framework that the app targets is installed on the target machine.
The most likely scenario is that you've failed to installed the .NET Core runtime at all or at least failed to install the correct version thereof to match what your project is targeting.
For Asp.Net Core 2.2 MVC.
1. Create web.config at the root on the Project.
2. Past this configuration:
<?xml version="1.0" encoding="utf-8"?>
<configuration>
<location path="." inheritInChildApplications="false">
<system.webServer>
<handlers>
<add name="aspNetCore" path="*" verb="*" modules="AspNetCoreModule" resourceType="Unspecified" />
</handlers>
<aspNetCore processPath="dotnet"
arguments=".\MyApp.dll"
stdoutLogEnabled="false"
stdoutLogFile=".\logs\stdout"
hostingModel="InProcess" />
</system.webServer>
</location>
</configuration>
I was having the same issue with Interserver.com.
Support was able to solve the problem by switching my application pool to 64 bit. From what I have read in regards to other Plesk hosting providers is that by default the scripts that create your virtual machine by default create the application pool in 32 bit. I'm guessing that AspNetCoreModuleV2 requires 64 bit, but that is just a guess. Happy that my site is running in process now.
I updated my ASP.NET Core project from RC1 to 1.0 RTM (with preview2 tooling), everything went fine. I can debug in Visual Studio without problems. Next I would like to upload the site on a Windows Server 2008 R2 and IIS 7.5. I installed the necessary Windows Hosting tools and created the web application in the IIS. The problem is, that after I tried to open the page, it returned a 404 error. As I see in the task manager, my application is running, but stops in listening mode.
In the log file I only see these entries:
Hosting environment: Production
Content root path: C:\inetpub\wwwroot\MySite
Now listening on: http://localhost:20706
Application started. Press Ctrl+C to shut down.
It seems like there is some problem with the IIS integration. My web.config file looks like this:
<?xml version="1.0" encoding="utf-8"?>
<configuration>
<system.webServer>
<handlers>
<add name="aspNetCore" path="*" verb="*" modules="AspNetCoreModule" resourceType="Unspecified" />
</handlers>
<aspNetCore processPath="..\..\approot\MySite\MySite.exe" arguments="" forwardWindowsAuthToken="true" stdoutLogEnabled="true" />
<httpErrors errorMode="Detailed" />
</system.webServer>
</configuration>
I tried some workarounds from GitHub, which affected the Startup.cs file's Configure method without any success.
Any ideas?
FYI.. This web.config file was missing in the app folder.
This file should be at: C:\wwwwroot\myapp\
<?xml version="1.0" encoding="utf-8"?>
<configuration>
<location path="." inheritInChildApplications="false">
<system.webServer>
<handlers>
<add name="aspNetCore" path="*" verb="*" modules="AspNetCoreModuleV2" resourceType="Unspecified" />
</handlers>
<aspNetCore processPath=".\XXX.exe" stdoutLogEnabled="true" stdoutLogFile=".\logs\stdout" hostingModel="InProcess" />
</system.webServer>
</location>
</configuration>
Don't forget to replace XXX.exe with the correct name of your Web API exe name.
Ok, I had multiple problems, but the two main reasons why my site didn't work:
I cannot start the code from two separate places. I originally put the wwwroot content under the wwwroot folder (not so suprising), and the rest to the approot. Now everything should be in the same folder.
My release versions didn't want to work. I must use the contents of the debug folder. I don't know why.
And now, everything is ok.

I am using VS2010 + C# + .Net 4.0 + IIS 7.5 + Windows 7. When I open an svc file (in IIS manager, right click the svc file and select browse) for a WCF project in IIS, there is an error like this, any ideas what is wrong?
This type of page is not served.

You may have to launch the command servicemodelreg –ia in Visual Studio command prompt.
If it's not working, check if you have "WCF http activation" feature installed (Add/Remove Programs - Turn Windows Features On or Off - Microsoft .Net 3.5.1).
UPDATE 1: Probably your application is hosted under .NET 2.0 App Pool. Go to IIS Manager and check for Basic Settings… link. Click Select button and you will see which option are you using. Change it to use .NET 4.0
UPDATE 2: Your web.config file seems incomplete. I suggest you to configure your service using WCF Configuration Editor tool. Launch it (make sure you are using .NET 4 version of the tool) and open your web.config file. Create service configuration and service endpoint configuration, then save it.
Its likely the mime types not setup correctly on IIS, try using the aspnet_regiis tool. Failing that, I'd recommend adding a mimetype to your virtual directory in iis for .svc files to be handled by the .NET runtime.
