Question

Is it possible to use Reactive Extensions (Rx) to create applications in .NET 3.5 that perform parallelization or is it limited in some way? I downloaded Rx from here http://www.microsoft.com/download/en/confirmation.aspx?id=26649 and after creating a simple project with referenced reactive assemblies, I failed to find any classes corresponding to Tasks in .NET 4.0. I’m trying to find classes for ‘Task’, but alas I can not find any. Am I doing something wrong?

Maybe the samples from the rx wiki can help you.

The simplest background task would be:

var o = Observable.Start
(
    () => 
    { 
        Console.WriteLine("Calculating..."); 
        Thread.Sleep(3000); 
        Console.WriteLine("Done."); 
    }
);

o.First();   // subscribe and wait for completion of background operation

But you may also want to look at the forkjoin examples.
