we are upgrading our servers and moved the asp.net core web api to the new servers with the following framework and runtime versions.
.net framework 4.7
.net core runtime 2.2.6
.net core windows server hosting 2.2.6
IIS URL rewrite Module
Getting a 404 error when trying to browse the application from IIS. Same error from postman too.
But when I run it from VS, I get the swagger screen and am able to post requests and get a response too. I tried uninstalling the runtime and hosting modules changing the apppool settings.
Currently the appPool is set to Networkservice, Unmanaged code, tried all the settings for appPoolIdentity. Nothing worked.
Tried enabling the FailedRequestTracing and this is what I see.
Looking for any helpful advices. thanks

This is my first time publishing a web forms project in ASP.NET. I have encountered may http error but this one i do not understand. My IIS version is 10.0
HTTP Error 404.17 - Not Found
The requested content appears to be script and will not be served by the static file handler.
I i have seen a lot of solutions in the internet there is one in common and this is running
C:\Windows\Microsoft.NET\Framework\v4.0.30319>aspnet_regiis -i in cmd.
But I do get this error:
Microsoft (R) ASP.NET RegIIS version 4.0.30319.0
Administration utility to install and uninstall ASP.NET on the local machine.
Copyright (C) Microsoft Corporation. All rights reserved.
Start installing ASP.NET (4.0.30319.0).
This option is not supported on this version of the operating system. Administrators should instead install/uninstall ASP.NET 4.5 with IIS8 using the "Turn Windows Features On/Off" dialog, the Server Manager management tool, or the dism.exe command line tool. For more details please see http://go.microsoft.com/fwlink/?LinkID=216771.
Finished installing ASP.NET (4.0.30319.0).
I check my .Net version and it is 3.5 and 4.8 on the Turn windows features on/off. I did select the 4.8 because if causes a lot of error. Or do I need to select it?
If I select the .Net 4.8 Version I get this error.
Could not load type 'System.ServiceModel.Activation.HttpModule' from assembly 'System.ServiceModel, Version=3.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'.
Which is easy to resolve? Or do I need to resolve both?
If you have any solutions please let me know.
Thanks in advance
Solved my problem.
Go to Turn windows feature on/off
Expand .NET Framework 4.8 Advanced
Services Expand WCF Services
Check HTTP Activation
Refresh Website and it should work!
When I am trying to run my asp.net project it is giving me error as:
"Unable to connect to ASP.NET development server error."
It was working well one day ago, but after I uninstalled and re-installed Visual Studio, now it is showing me Error in visual studio.I have no idea about this error please help me in this regard. Any help regarding this will be strongly appreciated.
Even I faced this problem. while installing the visual studio 2010 we need to install IIS component.Follow the steps for installing "IIS 6 management capability".
1.goto control panel>>Turned windows features on or OFF>>
2.Internet information services >> web management tools>> check out checkbox (IIS management console)
I'm trying to migrate an ASP.NET 2.0 app (WebForms) to ASP.NET 3.5. I've finally fixed a 500.19 IIS 7.5 error I was having. Now it will run, so long as I don't attempt to debug it. If I do attempt to debug it I get an error message. I've searched for help on this error and there's precious little out there. Here's the text of the error message:
Unable to start debugging on the web server. Check for one of the following.
The application you are trying to debug uses a version of the Microsoft .NET Framework that is not supported by the debugger.
The debugger has made an incorrect assumption about the Microsoft .NET Framework version your application is going to use.
The Microsoft .NET Framework version specified by you for debugging is incorrect.
Please see the Visual Studio .NET debugger documentation for correctly specifying the Microsoft .NET Framework version your application is going to use for debugging.
Well, as far as I know, I'm using the correct version of the .NET Framework (3.5) for this app. Although I am not as familiar with IIS 7.5 on Windows 7.
I found that I had to get into IIS and change the application pool that my upgraded ASP.NET app was using. It had been assigned to an application pool that's associated with .NET 4.0. I changed it to one related to .NET Framework 2.0.
