F# (at least in Visual Studio 2012) has both Control.Observable and Control.Event.

  • How are they related?
  • Which one should be used when?
  • Are there performance differences between the two?

I would also love to know what Haskell modules / packages / features the .NET IEnumerable / IObservable duality achieved with reactive extensions to .NET correspond to.
