Since .NET Framework 4.0, there has been a standard BlockingCollection<T> class, so we should prefer using this to create our own implementations such as BoundedBlockingQueue<T>. It contains all the required operations and allows us to choose different element storage strategies using different concurrent collections.

In spite of BlockingCollection<T> implementing the ICollection<T> interface, it is just a wrapper over any general concurrent collection that implements IProducerConsumerCollection<T>. The Blocking part of the collection name means that the Take method blocks until new elements appear in the collection. A more accurate name for this collection would be BoundedBlockingProducerConsumer<T>, since it also blocks the Add method when the maximum underlying collection capacity is reached.

Let's use BlockingCollection<T> to create a custom Producer/Consumer implementation that allows us to create a...
