Tutorial: https://learn.microsoft.com/en-us/aspnet/core/security/authentication/scaffold-identity?view=aspnetcore-6.0&tabs=visual-studio#scaffold-identity-into-a-razor-project-with-authorization

The tutorial is suppose to be for .net core 6.0 / the error message indicates there is a version discrepency...it wants to install for 7.0 (which I'm not running).

Any help appreciated.
