Rx extensions: Where is Parallel.ForEach?

Question

I have a piece of code which is using Parallel.ForEach, probably based on a old version of Rx extensions or the Tasks Parallel Library. I installed a current version of Rx extensions but cannot find Parallel.ForEach. I'm not using any other fancy stuff of the library and just want to process some data in parallel like this: Parallel.ForEach(records, ProcessRecord); I found this question, but I would not like to depend on an old versions of Rx. But I was not able to find something similar for Rx, so what's the current and most straight forward way to do that using a current Rx version? The project is using .NET 3.5.

No need to do all this silly goosery if you have Rx: records.ToObservable() .SelectMany(x => Observable.Start(() => ProcessRecord(x), Scheduler.ThreadPoolScheduler)) .ToList() .First(); (Or, if you want the order of the items maintained at the cost of efficiency): records.ToObservable() .Select(x => Observable.Start(() => ProcessRecord(x), Scheduler.ThreadPoolScheduler)) .Concat() .ToList() .First(); Or if you want to limit how many items at the same time: records.ToObservable() .Select(x => Observable.Defer(() => Observable.Start(() => ProcessRecord(x), Scheduler.ThreadPoolScheduler))) .Merge(5 /* at a time */) .ToList() .First();
