How do I chain Asynchronous Operations with the Task Parallel library in .NET 4?

Question

I\'m attempting to programmatically chain asynchronous operations in C#4, such as Writes to a given Stream object. I originally did this \"manually\", hooking callbacks from one

As far as I understand it, this is an unfortunate consequence of not being in control over when a task gets started. Since you never know when a task gets started, there can't be an overload like

precedingTask.ContinueWith(Task nextTask)

because once created, it might already be started when you get to 'ContinueWith'. Besides, it would also make a mess of types. What should be the type here:

precedingTask.ContinueWith(Task<..what?..> nextTask)

preceding returns a T, so next takes what and returns what? :) This could be solved with closures though.
