Windows Authentication .NET Core 9

Hello,

I’m trying Wisej 4 beta and looking forward to move projects over from Wisej 3.x .NET framework to Wisej 4 .NET Core 9.

Out of the box, if I create a new project from the WisejWebDesktopApplication template. What are the steps I need to take, running in the debugger, to get Windows Authentication to work in the IE browser that start when I run the program?

In .NET framework I could in properties for the project enable enable “Windows Authentication” and disable “Anonymous Authentication”.
Also in Web.Config I had this:

    <system.web>
        <customErrors mode="Off" />
        <authorization>
            <deny users="?" />
        </authorization>

This is the code I have so far, in .NET Core 9 that I think I need. Please correct me if this is not what I need:

Startup.cs:

using Microsoft.AspNetCore.Builder;
using Microsoft.Extensions.DependencyInjection;
using System;
using Wisej.Core;
using Microsoft.AspNetCore.Authentication.Negotiate; // Add this namespace for NegotiateDefaults
 
var builder = WebApplication.CreateBuilder(new WebApplicationOptions
{
    Args = args,
    WebRootPath = "./"
});
 
MGRegnskapWisej.Configure.ConfigureForWisej();
 
// 1) Register the Negotiate handler
builder.Services.AddAuthentication(NegotiateDefaults.AuthenticationScheme)
                .AddNegotiate();
// 2) Add authorization if you need [Authorize] attributes
builder.Services.AddAuthorization();
builder.Services.AddHttpContextAccessor();
 
var app = builder.Build();
 
// 3) Plug authentication/authorization into the pipeline
app.UseAuthentication();
app.UseAuthorization();
 
// Add Wisej.
app.UseWisej();
 
// Add FileServer middleware to serve content files excluding .json files.
app.UseWhen(
    context => !context.Request.Path.Value.EndsWith(".json", StringComparison.InvariantCulture),
    app => app.UseFileServer());
 
app.Run();

Program.cs:

using System;
using System.Collections.Specialized;
using System.Diagnostics;
using Wisej.Web;
 
namespace MGRegnskapWisej
{
    internal static class Program
    {
        /// <summary>
        /// The main entry point for the application.
        /// </summary>
        /// <param name="args">Arguments from the URL.</param>
        static void Main(NameValueCollection args)
        {
            Debug.Print(Application.User.Identity.Name);
            string s = Application.User.Identity.Name;  //  <--- I get null on this line
 
            Application.Desktop = new MyDesktop();
 
            Window1 window = new Window1();
            window.Show();
        }
    }
}

So far this is not working. Application.User.Identity.Name is null. There must be additional configuration steps I need to make somewhere to get this working.

Thanks.

Best regards
