Launching the project for the first time, without anything in App_Data, I had an error :

System.InvalidOperationException: Cannot provide a value for property 'SiteService' on type 'OCBlazorLib.Pages.Content'. There is no registered service of type 'OrchardCore.Settings.ISiteService'.

I changed the route of Home.razor from @page "/" to @page "/home" and then, I have been able to have the setup screen.

@agriffard Updated the home link to /home

@agriffard Updated the home link to /home

After the setup, I changed it back to "/" in order to get a root url.
