It helps, thank you.

services.AddTransient<icontrolpanel>(serviceProvider =>
var context = serviceProvider.GetRequiredService<ihttpcontextaccessor>().HttpContext;
var userHeader = context.Request.Headers["loggedInUser"];
if (string.IsNullOrEmpty(userHeader)) return new GuestControlPanel();
if ("admin" == userHeader) return new AdminControlPanel();
return new NormalUserControlPanel(userHeader);
