Error 500.19 Internal server error on IIS

There are lots of questions about this message error, I tried all the proposed solutions but none of them worked

I have a ASP .NET webapp, I registered the app to IIS and when I visit the page I get this error:

HTTP Error 500.19 internal server error The requested page cannot be accessed because the related configuration data for the page is invalid

Error code is: 0x8007000d

I post 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=".\ReviewerServices.web.exe" arguments="" stdoutLogEnabled="false" stdoutLogFile=".\logs\stdout" forwardWindowsAuthToken="true" />
  </system.webServer>
</configuration>

Here what I tried:

• issuing the command "aspnet_regiis.exe -i" after the installation
• assigning full permissions to the entire folder to the user IUSR and IIS_IUSRS
• checking the web.config for syntax errors (none found)
• tried to fudge a little bit the web.config file (looking for non printable ascii, encoding format and such)

It is so carefully documented by Microsoft in a step by step way,

You forgot to install ASP.NET Core Module for IIS.
