I should read an environment variable that I stored at the Windows operating system level, which contains an authentication token that my middleware class uses to authenticate me with my ASP.NET Core 8 Minimal API.
With
using APITest;using Microsoft.AspNetCore.Mvc;using Microsoft.EntityFrameworkCore;using Microsoft.IdentityModel.Tokens;var builder = WebApplication.CreateBuilder(args);// Estrai la variabile d'ambientevar Token = Environment.GetEnvironmentVariable("Token", EnvironmentVariableTarget.Machine);// Add services to the container.// Learn more about configuring Swagger/OpenAPI at https://aka.ms/aspnetcore/swashbucklebuilder.Services.AddEndpointsApiExplorer();builder.Services.AddSwaggerGen();var connectionString = builder.Configuration.GetConnectionString("ConWindows");builder.Services.AddDbContext<SqlServerDb>(options => options.UseSqlServer(connectionString));var app = builder.Build();// Configure the HTTP request pipeline.if (app.Environment.IsDevelopment()){}//temp testapp.UseSwagger();app.UseSwaggerUI();app.UseDeveloperExceptionPage();app.UseHttpsRedirection();// Aggiungi il middleware di autenticazione basata su token//app.UseMiddleware<TokenAuthMiddleware>();//Console.WriteLine("Token from Program.cs: " + Token); // Aggiungi questa riga per verificare il tokenapp.MapGet("/turni/abilitati", async ([FromServices] SqlServerDb db, ILogger<Program> logger) =>{ try { var turni = await db.Turni.Where(t => t.TurnoAbilitato == true).ToListAsync(); return Results.Ok(turni); } catch (Exception ex) { logger.LogError(ex, "Errore durante la ricezione dell'elenco turni!"); return Results.Problem("Errore durante la ricezione dell'elenco turni!"); }}).WithName("ElencoTurniAttivi").WithOpenApi();//metodo get che mi restituisce la variabile d'ambienteapp.MapGet("/env/", () =>{ var value = "Token Process: " + Environment.GetEnvironmentVariable("Token",EnvironmentVariableTarget.Process); var value2 = "Token User: " + Environment.GetEnvironmentVariable("Token", EnvironmentVariableTarget.User); var value3 = "Token Machine: " + Environment.GetEnvironmentVariable("Token", EnvironmentVariableTarget.Machine); return value +" - " + value2 +" - " + value3;}).WithName("Tet").WithOpenApi();app.Run();//crea metodo per modificare un turnoapp.MapPut("/ChiamaTurno/{id}", async ([FromServices] SqlServerDb db, int id, [FromBody] Turno turnoModificato, ILogger<Program> logger) =>{ try { var turno = await db.Turni.FindAsync(id); if (turno == null) { return Results.NotFound(); } turno.ProgressivoTurno +=1; turno.Serviti +=1; turno.RepartoVariabile = turnoModificato.RepartoVariabile; await db.SaveChangesAsync(); return Results.Ok(turno); } catch (Exception ex) { logger.LogError(ex, "Errore durante la chiamata del turno."); return Results.Problem("Errore durante la chiamata del turno."); }}).WithName("Aggiorna").WithOpenApi();app.Run();public class SqlServerDb : DbContext{ public SqlServerDb(DbContextOptions<SqlServerDb> options) : base(options) { } public DbSet<Turno> Turni { get; set; } // Aggiungi altre DbSet per altre tabelle qui.}public class Turno{ //? significa che il campo può essere null per evitare errori public int Id { get; set; } public string?

I also tried with the process, user, machine targets but I notice that these only work in debug from Visual Studio, but they don't work as soon as I publish the app in IIS.
environment variables are only output with mapget method. From console.writeline variables are empty
