Remarks
The SemaphoreSlim provides a lightweight semaphore class that doesn't use Windows kernel semaphores.
All public and protected members of SemaphoreSlim are thread-safe and may be used concurrently from multiple threads, with the exception of Dispose, which must only be used when all other operations on the SemaphoreSlim have completed.
