问题 I know that calling the StateHasChanged() method notifies the component that the state has changed and that it should re-render.

问题 I am trying to implement a basic custom Auth provider in my server side blazor project, but I am having some difficulty implementing the 'IsAuthenticating' property correctly.

Specifically this line of code: if(IsAuthenticating) { return null; <---- This line

问题 I'm currently writing a (Server side) Blazor application that includes the default AzureAD Authentication. This works well for authenticated users - challenging on the entrance ( _Host.cshtml ) file, redirecting and then back once authenticated. I need to have a couple of pages not requiring authentication - I don't want the user being challenged and redirected to Microsoft. What is the correct way to do this? I have experimented with the AllowAnonymousAttribute , the AllowAnonymousToPage
