The Parallel Stacks Window is a valuable tool in debugging multi-threaded applications as we can have a view of all threads at once and their call stacks in any given time. It allows us to see the delegation of work to different threads as they are made free and as they are indicated by the compiler to work.

Now we will use the '''Parallel Watch Window''' to view the variable i, and its value in the different threads as we go through the stack frames as determined by our breakpoints.
