Using Parallel.ForEach in .NET
Just watching a Pluralsight video about VB.NET and the CLR and I came across the System.Threading.Tasks namespaces Parallel static class.
It seems a nice tidy way of multi threading when iterating over things. I think I have been missing a trick! :-)
Essentially you just pass the collection as the first parameter and a delegate as the next. See the example or just Google it.
You can also whip the .AsParallel(); extension method on the end of your Linq queries for similar parallel joy.
It's possible I knew about this before but the rediscovery is very pleasing indeed.
