Content displayed during asynchronous authentication in ASP.NET Blazor

<AuthorizeView>
    <Authorized>
        <h1>Hello, @context.User.Identity.Name!</h1>
        <p>You can only see this content if you're authenticated.</p>
    </Authorized>
    <Authorizing>
        <h1>Authentication in progress</h1>
        <p>You can only see this content while authentication is in progress.</p>
    </Authorizing>
</AuthorizeView>

This approach isn’t normally applicable to Blazor Server apps. Blazor Server apps know the authentication state as soon as the state is established. Authorizing content can be provided in a Blazor Server app’s AuthorizeView component, but the content is never displayed.
