Aurelia Host in AspNet Kestrel Refresh problem

Hi all,

I would like to know why when I make my site hosted from ISS ( while work on the site) and i press F5 it reload correctly… when I host my site in a Kestrel Self-host server and I press F5 it lost all the content.
It seems like if he try to find a physical page.
For example:
my url “localhost:41430/profile” send me in my profile page but when I press F5 to reload the page became white. All lost.

Thank you if you could help me,
Andrea
