publishing fresh project on IIS


I have created new project core without doing any changes and use the created default files. I can successfully run this using the debug mode, but if I am going to publish it on IIS it will give me error: HTTP Error 500.19 - Internal Server Error and here is the error details:

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

Error code:


I already tried to modify the web.config to point the processPath to my dotnet location but it still have the same error result:

<?xml version="1.0" encoding="utf-8"?>
  <location path="." inheritInChildApplications="false">
        <add name="aspNetCore" path="*" verb="*" modules="AspNetCoreModule" resourceType="Unspecified" />
      <aspNetCore processPath="C:\Program Files\dotnet\dotnet.exe" arguments=".\WebApplication1.dll" stdoutLogEnabled="false" stdoutLogFile=".\logs\stdout" />
<!--ProjectGuid: d4e1dda9-f8ba-4752-883d-43c86faa3c60-->

I am not yet sure if this one is related to my IIS setup configuration. Any suggestion/comments if encountered this. TIA

then assign permission to the site folder. 1)open iis manager, select your site.

2)right-click on-site and select Edit permission.

4)one pop up window will open in that select add.

5)in select user or group windows type "iusr" in object name text box and click ok and assign full permission.

6)Repeat the above steps and add "iis_iusrs" and "IIS AppPool\" user permission.

7)After doing changes restart the iis server.

You need to install the “ASP.NET Core/.NET Core: Runtime & Hosting Bundle” on to the server.

you could also set load user profile to true in iis application pool advance setting.
