Am trying to install a blazor 8 server app on IIS. Everything works fine within VS2022, but once I deploy the files to IIS I get some errors.
I've tried <base href="/BlazorApp4/" /> or <base href="/" /> and <base href="..." />
and nothing seems to work. The app works fine as a website and these errors are result of trying to setup as application. Let me know, if anyone has had any issues with this. Are we missing a update or something.
Thanks

Could you please tell me how you setup as application? Host it inside another website in IIS? If possible, please share the IIS folder to let us check it.

I have experienced the same issues, which only have occurred once starting to use .Net 8's Blazor Web App template. This was not an issue before. In my case, I am hosting the application in IIS's "Default Web Site". (Ex: "{domain}/{MyAppName}") I have similarly tried variations of the base tag and also tried to assign a value in the Program.cs file as instructed here: https://learn.microsoft.com/en-us/aspnet/core/blazor/host-and-deploy/?view=aspnetcore-9.0&tabs=visual-studio#app-base-path The suggestions will cause the app to work sometimes but will in a few cases (like reloading a page) will result in missing resources due to incorrect URL.

The base href should match the iis app name and sets the base path for relative links. The links should be relative, and not start with a “/“.
