I want to use Microsoft Identity for the 2FA for my Backend/Frontend Users.

I have done this with pure dotnet core project by using the scaffolding and code generation methods.

I have also tried this on an umbraco 9 rc 4 project. After successfully scaffolding Identity and run my application I get the following error.
