How to fix badly configured web.config created by a visual studio default project template

0

I'm trying to set up CI and I'm having issue with the generated web.config file after my deployment.

My main question is what do I need to do either to my project in Visual Studio or my server to fix this web.config issue.

Steps I've done.

  1. I've created a ASP.NET Core Web Application project in Visual studio. (It runs when debugging using IIS Express)
  2. I connected it to a repo in Azure DevOps.
  3. Used the default agent pool to build the web artifact
  4. Set up a local agent on the server that will be hosting the site.
  5. Ran the pipeline and passed.
  6. Checked site has been deployed.
  7. Tried running the site and got a 500.19 Error

In visual studio I can use IIS Express to run a localhost of the site and it works.

On my hosted machine it says that the web.config is badly configured.

HTTP Error 500.19 - Internal Server Error

The requested page cannot be accessed because the related configuration data for the page is invalid.

Detailed Error Information:

The generated web.config

<?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=".\Web Content.dll" stdoutLogEnabled="false" stdoutLogFile=".\logs\stdout" hostingModel="inprocess" />
    </system.webServer>
  </location>
</configuration>
<!--ProjectGuid: [A Guid]-->

Using 'https://elmah.io/tools/configvalidator/' it tells me that (8,125) The 'hostingModel' attribute is invalid - The value 'inprocess' is invalid according to its datatype 'String' - The Enumeration constraint failed.

The previous version of the site worked (before connecting my CI to it). It was a simple site with just an Index page, it had the following web.config.

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
    <system.webServer>
        <defaultDocument>
            <files>
                <clear />
                <add value="index.html" />
                <add value="Default.asp" />
                <add value="iisstart.htm" />
            </files>
        </defaultDocument>
    </system.webServer>
</configuration>

My main question is what do I need to do either to my project in Visual Studio or my server to fix this web.config issue.
