Thank you, however, when I click on the link you've provided I get the same 404 error message.
Steps to recreate the issue:
https://github.com/aspnetzero/aspnet-zero-core/releases/download/v14.0.0-rc.1/metronic-8.2.8.zip
Are you saying the only way to download the Metronic Theme is to create a GitHub User Account and then add that GitHub user to my ASPNET Zero account?
