I have a simple Blazor Server .NET 8 App that I'm trying to publish. When I run it in development mode it has no issues.

When I attempt to publish and run in Production I see the following. Am I doing something wrong here?

var app = builder.Build();

// Configure the HTTP request pipeline.
//if (!app.Environment.IsDevelopment())
//{
//    app.UseExceptionHandler("/Error", createScopeForErrors: true);
//    // The default HSTS value is 30 days. You may want to change this for production scenarios, see https://aka.ms/aspnetcore-hsts.
//    app.UseHsts();
//}

//app.UseHttpsRedirection();

I figured this out - I was looking in the wrong spot: it publishes to:

\BlazorTron\bin\Desktop\win-unpacked
