User profile empty in HttpContext in azure web app

Question

I am using an azure web app service with my identity provider Auth0. I got this working but whenever I login in my website hosted on azure the user profile is not loaded in HttpContext. This is working locally in IIS Express. Any idea what I might be missing?

This is my code to get the logged in user profile:

[Inject]
    private IHttpContextAccessor HttpContextAccessor { get; set; }
    private string loginId;

    /// <summary>
    /// On initialized
    /// </summary>
    /// <returns></returns>
    protected override async Task OnInitializedAsync()
    {
        await LoadInvoiceTypes();
        this.loginId = HttpContextAccessor.HttpContext.User.Claims.FirstOrDefault(c => c.Type == "http://schemas.xmlsoap.org/ws/2005/05/identity/claims/nameidentifier")?.Value;
    }

I did a bit of logging in the website and it seems that the HttpContext is null.

Thanks in advance!

Apparently it is advised in blazor to use the AuthenticationStateProvider. This is giving me the logged in user in azure as I expected it should be.

    protected string loginId;

    [Inject]
    private AuthenticationStateProvider AuthProvider { get; set; }

    protected override async Task OnInitializedAsync()
    {
        var authState = await AuthProvider.GetAuthenticationStateAsync();
        this.loginId = authState.User.Claims.FirstOrDefault(c => c.Type == "http://schemas.xmlsoap.org/ws/2005/05/identity/claims/nameidentifier")?.Value;
        await base.OnInitializedAsync();
    }

Thanks for your input.
