Left nav menu 404 after publish to IIS application dir instead of root

[fdgit]

Are there changes need to be made to publish to an application subdirectory
in IIS? (for example http://myapp/serene as oppesed to http://serene).

When I publish to an application directory ("/myapp") rather than the root, the login page works
but my left menu items are all missing /myApp/, so the links are 404.

If I add a Url parameter to the assembly: NavigationLink(..., Url="myapp/myThing") in *navigation.cs, then the
left menu URLs are correct (they begin with /myApp/), but the drilldown into their dialogs fails to find the dialog templates
and the urls appear malformed (like this: http://localhost/myapp/#categorypart-subItempart/12345)

In desperation have tried

• adding app.UsePathBase("/myApp/"); to startup cs
• adding a tag
• adding ~ in the Route on the controller action.

I wrote a small core core app and all its links are correct when published to /myapp/ rather than root, and
I see the demo is hosted under an application directory, so I must be missing a key point)
Thank you

It's not serenity related. It's just configuration a .net 5 application for IIS. Because of that I convert your issue to discussion. @fdgit Please use discussion for Q&A next time.

I had to add the correct URL parameter to the NavigationLink attributes, being sure that they matched each modules *Form.cs:

-[assembly: NavigationLink(9000, "Administration/User Management", typeof(Administration.UserController), icon: "fa-users")]
+[assembly: NavigationLink(9000, "Administration/User Management", typeof(Administration.UserController), icon: "fa-users", Url = "Administration/User")]
