Can't check IsTwoFactorClientRemembered when in ServerInteractive mode

[geistchevalier]

I'm playing around with server side render Blazor the new .net 8.0, I noticed that if I set the rendermode of my login page (login.razor) to @rendermode InteractiveServer, causes it to throw an error when I run await SignInManager.IsTwoFactorClientRememberedAsync in a separate injected helper class (loginhelper.cs). It would fail with the message of onstarting cannot be set because the response has already started.

Drilling down I found that it would fail at SignInManager<TUser>.Context.AuthenticateAsync(IdentityConstants.TwoFactorRememberMeScheme)

It executes just fine if I removed the @rendermode InteractiveServer

I understand enough to recognize that this is related to the HttpContext, but not enough to understand the flow to think of a fix/workaround. Is my only option to remove the InteractiveServer rendermode if I want to check if the current user passes the IsTwoFactorClientRememberedAsync check?

I´d like to know that too. Got the same problem.
