Monitor.Enter acquires the lock on the object no other thread can access the object Monitor.Wait [When a thread calls Wait it releases the lock on the object and enters the object's waiting queue. The thread that currently owns the lock on the specified object invokes this method in order to release the object so that another thread can access it. The caller is blocked while waiting to reacquire the lock. This method is called when the caller is waiting for a change in the state of the object that will occur as a result of another thread's operations on the object.] AutoResetEvent is used for thread communication via signals. Flavor of AutoResetEvent is that you have not to call Reset.

Monitor.Enter simply creates an exclusive lock on the specified object. Now after executing the required task you must have to release the object and let the other threads use the object. This is where Monitor.Wait comes into play. Monitor.Wait Releases the lock on an object in order to permit other threads to lock and access the object. The calling thread waits while another thread accesses the object. Pulse signals are used to notify waiting threads about changes to an object's state.
