Specifying a Thread's Name when using Task.StartNew

Well, this works:

class Program {
    static void Main(string[] args) {
        var task = Task.Factory.StartNew(() => {
            Thread.CurrentThread.Name = "foo";
            Thread.Sleep(10000);   // Use Debug + Break to see it
        });
        task.Wait();
    }
}

There's a problem however, the threadpool thread gets recycled and won't change its name. This can be confusing, you'll see it running later executing entirely different code. Be sure to take note of this. Your best bet is otherwise to use the Location column in the Debug + Windows + Threads window to find the task back.

Not a Thread-name for sure.

Threads and tasks are not 1-to-1 related.

You can use the Task.Id to track it.

I prefer to use Thread.CurrentThread.ManagedThreadId. It's not as good as a name, but does help track the specific work for a thread.
