Quick Quiz on Tasks

1. New C# Console Project in VS2008
2. Add Reference to System.Threading.dll (from Parallel Extensions June CTP)
3. Replace the entire contents of Program.cs with the following (overly simplified extract of a more complex piece of code):
using System;
using System.Threading.Tasks;

static class Program
static void Main()
Task t1 = Task.Create(delegate
Task t2 = Task.Create( // breakpoint #1
(o) =>
Console.WriteLine(o.ToString()) // breakpoint #2
, "hey");
t2.Wait(); // breakpoint #3
t1.Wait(); // breakpoint #4

Console.ReadLine(); // breakpoint #5

4. Insert a breakpoint (F9) wherever there is a comment.

A. Without running the project, what can you predict about which breakpoints will be hit and in what order?
B. Can you predict at each breakpoint, which of the two variables (t1, t2) is in scope (e.g. if they were in the Watch window)?
