How to use: System.Collections.Concurrent

Question

I am trying to add using System.Collections.Concurrent and it is not working.

The type or namespace name 'Concurrent' does not exist in the namespace 'System.Collections' (are you missing an assembly reference?)

Did you add a reference (System.Collections.Concurrent) in your project ? — Bushuev, Apr 08 '16 at 11:30
I was using .net 3.5..... I have since changed it to 4.5 and is now working. If someone wants to write answer feel free. — meme, Apr 08 '16 at 11:32

Your ConcurrentQueue is only available from .NET 4. Upgrade your project to at least .NET 4.0.
