C# atom reference type equivalent to clojure atom

Question

Is there a C# BCL equivalent to Clojure atom, something like Atom<T> that provides atomic swap/reset semantics for reference type T ? .NET has immutable collections so so I could see using this class just like in Clojure.

Answer 1

C# has the Interlocked class:

you can do swaps with Interlocked.CompareExchange generically:
