Sitecore Experience Commerce Installation HTTP Error 500.19 – Internal Server Error

Recently installed SitecoreXC 9 initial version on my PC using Sitecore SIF. While running the installation script came across following error.

Error Information:
Module IIS Web Core
Notification Unknown Handler Not yet determined
Error Code 0x8007000d
Config Error Config File \\?\C:\inetpub\wwwroot\SitecoreIdentityServer\web.config

I checked C:\inetpub\wwwroot\SitecoreIdentityServer/Web.config and found the issue is related to .Net Core but .Net core 2.0.6 was already installed. So had another look at Install the .NET Core Windows Server Hosting bundle section on https://docs.microsoft.com/en-us/aspnet/core/host-and-deploy/iis/index?tabs=aspnetcore2x and found below line

Important! If the hosting bundle is installed before IIS, the bundle installation must be repaired. Run the hosting bundle installer again after installing IIS.

I’d recently upgraded server from 2012 to 2016 so this might have corrupted .Net Core. Followed below step

  1. On the .NET Core runtime download page ( https://www.microsoft.com/net/download/dotnet-core/runtime-2.0.6 ) under Windows, selected the Server Hosting Installer link to download the .NET Core Windows Server Hosting bundle and repaired the installer.
  2. Restarted the server
  3. Browsed https://localhost:5050/

All good !
