Page not found

Hello,

I created an application .NET 9 with Server side with Balzor Studio in Trial mode to evaluate. When I execute from Blazor Studio it's ok but when I run from VS2022 I get this error :

This localhost page can’t be found
No webpage was found for the web address: https://localhost:5001/index.html
HTTP ERROR 404

Do you have an idea what's wrong ?

thanks,

If you enter a web page it must exist or be a valid route.
If you don't enter a route it will display the default razor page configured.
E.G. https://localhost:5001
