The previous count of the SemaphoreSlim.

Exceptions

ObjectDisposedException

The current instance has already been disposed.

SemaphoreFullException

The SemaphoreSlim has already reached its maximum size.

Remarks

A call to the Release() method increments the CurrentCount property by one. If the value of the CurrentCount property is zero before this method is called, the method also allows one thread or task blocked by a call to the Wait or WaitAsync method to enter the semaphore.
