WithHttpEndpoint working in IIS Express not IIS local

[beinguam]

When I used IIS Express in the Properties of the project (in the Web tab) the metrics page works just fine, but if I used Local IIS instead it doesn't work at all. Thoughts?

What does it mean "doesn't work at all" ? What HTTP code you getting, whats in IIS log ?

WithHttpEndpoint is using HttpListener and is tailored to be used inside standalone exe (console program etc). If your app is running inside IIS (regular or Express), OWIN adapter is much better option...

Thanks for the suggestion - it is unusual - no error in the logs or http code, just a blank browser when I hit it...
