Mutex and Semaphore

Explore how Mutex and Semaphore synchronization primitives manage thread access to shared resources in C#. Understand their use cases and methods in .NET to write safer, more efficient multithreaded code.

We'll cover the following...

Synchronization using mutex

The word mutex stands for mutual exclusion. It’s a special object that can restrict access to a critical section of the code. In essence, there’s nothing much that separates a mutex from the lock statement or the Monitor class. We create a mutex object and, whenever we enter a critical section, we acquire the lock for the mutex. If the mutex has already been acquired by another thread, then the thread has to wait until the mutex is released.

Note: The mutex in .NET is represented by a class called Mutex, which resides in the System.Threading namespace.

Unlike the lock statement and ...
