I want to test my ASP.Net Core 2.0 Hello World Api on localhost.

I Created the project using VS2017 File->New Projecct-> .Net Core -> ASP.NET Core Web Application -> Empty

It ran fine in the debugger

Next I right clicked the solution and selected publish to create the publish folder.

I copied the contents of the publish folder to c:\inetpub\wwwroot

I set the application pool to No Managed Code and ran Iisreset

When I browse to localhost I get

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 contents of web.config is

<?xml version="1.0" encoding="utf-8"?>
      <add name="aspNetCore" path="*" verb="*" modules="AspNetCoreModule" resourceType="Unspecified" />
    <aspNetCore processPath="dotnet" arguments=".\WebApplication1.dll" stdoutLogEnabled="false" stdoutLogFile=".\logs\stdout" />
<!--ProjectGuid: e0c1b13d-2f11-4e4f-9b5d-3150bdecd831-->

I don't think it is a permissions thing because before I pasted the project I had a simple index.html and localhost worked fine.

    jexusmanager.com/en/latest/tutorials/oob-500.html Jexus Manager would tell you which OOB module is missing. In your case, very likely that .NET Core server bundle is missing. – Lex Li May 19 '18 at 10:35
  • I guess looking at web.config, that is the only candidate. Why is the publish not including it? – kirsten g May 19 '18 at 18:18
