TaskCompletionSource<T> for Silverlight?

just searching for a way to use the TaskCompletionSource class in Silverlight.

So first off, will it be available in Silverl开发者_如何学编程ight ver 5?

Second, are Reactive Extensions a good way to go?

Third, I came across PowerThreading from Jeffery Richter. Is this still a good way to go with Silverlight?

there's a port here (which I'm trying... assuming that pushing Silverlight 5 RC to a client even for testing is probably a bad thing)

Yes, TaskCompletionSource<T>, as well as the whole Task Parallel Library, is available in Silverlight 5.

Reactive Extensions are great, really a higher level way of thinking about events and async operations. Definitely recommended for use in .NET, Silverlight, and JavaScript projects.

I don't recommend Richter's PowerThreading library now; with the TPL making its way into SL 5, there's little use for his library, IMO.
