ASP.NET Core page not found when publishing to IIS

Question

I updated my ASP.NET Core project from RC1 to 1.0 RTM (with preview2 tooling), everything went fine. I can debug in Visual Studio without problems. Next I would like to upload the site on a Windows Server 2008 R2 and IIS 7.5. I installed the necessary Windows Hosting tools and created the web application in the IIS. The problem is, that after I tried to open the page, it returned a 404 error. As I see in the task manager, my application is running, but stops in listening mode.

In the log file I only see these entries:

Hosting environment: Production
Content root path: C:\inetpub\wwwroot\MySite
Now listening on: http://localhost:20706
Application started. Press Ctrl+C to shut down.

It seems like there is some problem with the IIS integration. My web.config file looks like this:

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <system.webServer>
    <handlers>
      <add name="aspNetCore" path="*" verb="*" modules="AspNetCoreModule" resourceType="Unspecified" />
    </handlers>
    <aspNetCore processPath="..\..\approot\MySite\MySite.exe" arguments="" forwardWindowsAuthToken="true" stdoutLogEnabled="true" />
    <httpErrors errorMode="Detailed" />
  </system.webServer>
</configuration>

I tried some workarounds from GitHub, which affected the Startup.cs file's Configure method without any success.

Any ideas?

FYI.. This web.config file was missing in the app folder. This file should be at: C:\wwwwroot\myapp\

<?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=".\XXX.exe" stdoutLogEnabled="true" stdoutLogFile=".\logs\stdout" hostingModel="InProcess" />
    </system.webServer>
  </location>
</configuration>

Don't forget to replace XXX.exe with the correct name of your Web API exe name.
