Background In the ancient days of the .NET Framework, there was a RouteDebugger that outputs routing information for the current page in an MVC or web API app, or sees all the routing information registered in the app. The latest version of its NuGet package is 2.1.5, updated in 2016, from an article by Phil Haack 12 years ago https://haacked.com/archive/2008/03/13/url-routing-debugger.aspx …
