What part of this doesn�t work?

Each time you add an async query the return value is a new AsyncParallelTask. So you can do this:

var asyncParallelTask = AsyncParallelTask.Create();

var t2 = asyncParallelTask.AddAsyncQuery(1, x => mgr.Customers);

var t3 = t2.AddAsyncQuery(2, x => mgr.Employees);

t3.Execute(�);

Is there a way to create AsyncParallelTask as a variable and then add queries to it? For example:

var asyncParallelTask = AsyncParallelTask.Create();

asyncParallelTask.AddAsyncQuery(1, x => mgr.Customers);

asyncParallelTask.AddAsyncQuery(2, x => mgr.Employees);

asyncParallelTask.Execute(cb => {
((EntityFetchedEventArgs )cb.CompletionMap[1])
.Result.ForEach(c => Debug.WriteLine(c.CompanyName));
((EntityFetchedEventArgs )cb.CompletionMap[2])
.Result.ForEach(e => Debug.WriteLine(e.LastName));
});

It would sure be nice to dynamically build these, so I want to ask before I give up on this approach. Obviously, the above does not work.

Thanks!
