Answer
Differences:
- lock/Monitor: lightweight, thread-level.
- Mutex: cross-process synchronization.
- Semaphore: limits concurrent entries.
- SpinLock: busy-wait for low contention.
- ReaderWriterLockSlim: optimized for read-heavy workloads.
Quick Answer
lock and Monitor: lightweight, process-local, same thread only. Mutex: cross-process, heavier, supports named mutexes. Semaphore: limits N concurrent threads. SpinLock: avoids context switch for very short critical sections. ReaderWriterLockSlim: allows many concurrent readers but exclusive write access.
