How do I access HttpContext.Current in Task.Factory.StartNew?

Question

I want to access HttpContext.Current in my asp.net application within

Task.Factory.Start(() =>{
    //HttpContext.Current is null here
});

Answer 1

As David pointed out, HttpContext.Current will not work all the time. In my case, about 1 of 20 time, CurrentContext will be null. End up with below.

string UserName = Context.User.Identity.Name;

System.Threading.Tasks.Task.Factory.StartNew(() =>
{
    UserName ...
}
