I've confirmed that there is no authentication in the C# code base.

I've followed this base article on how to configure IIS 10 (mine is on Win server 2019).

I publish from VS2019, the .Server project and copied that "publish" file folder to the IIS server.

I can't determine what I've done wrong.

I've checked that the Hosting Bundle is listed for IIS:
