Expand the Rx vs Task discussion

[LeeCampbell]

List the (dis)advantages with Rx and Task

Rx

• No way to provide Back pressure e.g. from x in xs from from content in Download(x)....how do I throttle so I dont have more than 5 calls to Download at once. (Maybe with Merge).
• Clumsy for Single value sequences. A bit like using an Array to return a single value.

Task

• Async/Await is really awesome. Finally Begin/EndAsyn pattern can go die.
• Painful cancellation paradigm. Arguments that suggest somethings are not cancellable so should not be built in seem very flaky.
• Obviously only for single values
• Cant compose, but not as nicely as Rx (IMO).
• Eager. If you have a task it has started running.
• Pre task: Einstien, With Task : Elvis, With await : Mort. Problem is, Concurrency is not a Mort problem space.
