Synchronizing Access to Shared Resources

Monitor

Synchronize access to objects.

• The Monitor class allows you to synchronize access to a region of code by taking and releasing a lock on a particular object by calling the Monitor.Enter, Monitor.TryEnter, and Monitor.Exit methods.
• You can also use the Monitor class to ensure that no other thread is allowed to access a section of application code being executed by the lock owner, unless the other thread is executing the code using a different locked object.

Semaphore

Use the Semaphore class to control access to a pool of resources.

• Threads enter the semaphore by calling the WaitOne method, which is inherited from the WaitHandle class, and release the semaphore by calling the Release method.

Mutex

A synchronization primitive that can also be used for inter-process synchronization.

• Mutex is a synchronization primitive that grants exclusive access to the shared resource to only one thread.
• If a thread acquires a mutex, the second thread that wants to acquire that mutex is suspended until the first thread releases the mutex.
• Documentation: https://docs.microsoft.com/en-us/dotnet/api/system.threading.mutex?view=net-6.0

Interlocked

Provides atomic operations for variables that are shared by multiple threads.

• The methods of this class help protect against errors that can occur when the scheduler switches contexts while a thread is updating a variable that can be accessed by other threads, or when two threads are executing concurrently on separate processors.
• The members of this class do not throw exceptions.
