Commonly Used Types: System.Collections.Concurrent.ConcurrentDictionary<TKey, TValue> System.Collections.Concurrent.ConcurrentQueue<T> System.Collections.Concurrent.ConcurrentBag<T> System.Collections.Concurrent.BlockingCollection<T> System.Collections.Concurrent.ConcurrentStack<T> When using NuGet 3.x this package requires at least version 3.4.

System.Collections.Immutable by: Microsoft

This package provides collections that are thread safe and guaranteed to never change their contents, also known as immutable collections.
