ApplicationContext does not have user Blazor Server

[CProsRodneyWorkman]

Describe the bug
I have a service that calls Portal Create and it found an authenticated user from the HttpContextAccessor moments later the BusinessBase Create method ApplicationContext does not have a user.

Version and Platform
Csla.Blazor 6.0.0
OS: Windows, Linux, iOS, Android, etc.
Platform: Blazor Server Side

Code that Fails

    [Create, RunLocal]
    private void Create()
    {
        if (this.ApplicationContext.Principal.Identity==null)
            throw new NullReferenceException("Application User is missing");

        Id = Guid.NewGuid();
        base.Child_Create();
    }

Stack Trace or Exception Detail
Provide a stack trace, or at least detailed information about the exception.

Additional context
In my Login.cshtml.cs I set the Principal
await HttpContext.SignInAsync(
CookieAuthenticationDefaults.AuthenticationScheme,
principal,
authProperties);

        ApplicationContext.Principal = principal;


    public AnimalEdit CreateAnimal()
    {

        var identity = HttpContextAccessor.HttpContext.User.Identity;
        if (identity.IsAuthenticated)
            return AnimalEditPortal.Create();
        else
            return null;
    }

This sounds like a bug, I'll have to look into this. Thank you for reporting!

@CProsRodneyWorkman I should confirm - this is with the data portal using LocalProxy right?

[CProsRodneyWorkman]

Here is my configuration.
IServiceCollection c = builder.Services.AddCsla(o => o
.DataPortal(dpo => dpo
.AddServerSideDataPortal()
.UseLocalProxy()));

[rockfordlhotka]

Oh, looking at your config, I'm pretty sure the problem is that you haven't brought in the services necessary for aspnetcore or server-side Blazor:

builder.Services.AddCsla(o => o
  .AddAspNetCore()
  .AddServerSideBlazor()
  .DataPortal(dpo => dpo
    .AddServerSideDataPortal()
    .UseLocalProxy()));

or really just this:

builder.Services.AddCsla(o => o
  .AddAspNetCore()
  .AddServerSideBlazor());

because the data portal defaults to the configuration in that code.

All the services necessary to properly manage the user principal in aspnetcore and server-side Blazor (which is an intricate process) are enabled by the AddAspNetCore and AddServerSideBlazor methods.

I added a new BlazorServerExample project to the repo that demostrates the basics.
