Hello,

I've followed the installation procedure for Umbraco 10 and once Umbraco was installed, with dotnet new umbraco I decided to switch from Startup.cs to the new .NET 6 default configuration that includes only the Program.cs. Then, something weird started happening. Even though I could start it and see the website just fine, the /umbraco url stopped working and nothing I could do seemed to bring it back. Is the middleware firing when using this configuration?

using MyProject.Core.Extensions;

WebApplicationBuilder builder = WebApplication.CreateBuilder(args);

// Add services to the container.
builder.Services.AddControllers();

IWebHostEnvironment env = builder.Environment ?? throw new ArgumentNullException(nameof(builder.Environment));
IConfiguration config = builder.Configuration ?? throw new ArgumentNullException(nameof(config));

builder.Services.AddUmbraco(env, config)
    .AddBackOffice()
    .AddWebsite()
    .AddComposers()
    .AddCustomContentFinders()
    .SetContentLastChanceFinder<MyProject.Core.ContentFinders.Error404PageContentFinder>()
    .Build();

WebApplication app = builder.Build();

// Configure the HTTP request pipeline.
app.UseUmbraco()
    .WithMiddleware(applicationBuilderContext =>
    {
        applicationBuilderContext.UseBackOffice();
        applicationBuilderContext.UseWebsite();
    })
    .WithEndpoints(endpointBuilderContext =>
    { 
        endpointBuilderContext.UseInstallerEndpoints();
        endpointBuilderContext.UseBackOfficeEndpoints();
        endpointBuilderContext.UseWebsiteEndpoints();
    });

app.Run();

It seems like the middleware is completely ignored or so it makes me think. Anyone ran into this?
