Answer 1

there is no proper documentation at this point. the issue is blazor server uses cookie authentication and blazor WASM typically uses bearer tokens. You need to add code to pass the server jwt tokens to the client via persistant user state, and a custom authorization provider for the client version.

see these threads:

https://github.com/dotnet/AspNetCore.Docs/issues/29452

the latest template supports individual accounts. this is has the sample client authentication provider initialized by the server code. you should change the server code to use azure ad authentication.
