Using Dashboard when application uses Global.asax.cs

The discussion here indicates that the Dashboard is not available if the application uses Global.asax.cs. I have a truly ancient ASP.NET web application using Global.asax.cs which cannot be changed substantially to become ‘modern’

Perhaps I am late to the discussion, but , is there any way to get the dashboard functionality to run at all?

For example, can I create a simple little app that just starts the dashboard which can be used to monitor all the Hangfire stuff from other web applications using Hangfire?

Any feedback on this?
